- [Tony] Could it be that aliens are leaving evidence

of their visitations on Earth?

- The locals know to avoid this place at all costs.

- [Tony] And if so, what are they trying to tell us?

- This object was simply unbelievable.

- I've never seen any device that can stop on a dime

and take off at maximum velocity.

- [Tony] We found images that appear to be so unusual,

some people question if they're from our world at all.

- [George] Some believe that when you first look at these,

they scream alien.

- [Tony] On this special episode

of "The Proof Is Out There: Alien Edition,"

our team of top experts will investigate compelling evidence

of extraterrestrials on Earth.

- We have physical, deposited evidence,

which is absolutely mind blowing to me.

- [Tony] And then, we'll pass a verdict.

- One theory about this thing is that it is not of this world.

- These are not a hoax.

- The proof starts now.

[dramatic music]

Good evening and welcome to "The Proof Is Out There."

When a car tears out, it leaves behind skid marks.

But what does a UFO leave behind?

We're going back more than 50 years for this first one

in what's been called

some of the most credible UFO evidence of all time.

November 2nd, 1971, it's evening in the small town

of Delphos, Kansas.

16-year-old Ron Johnson is on his family farm

when he suddenly says he sees

a bright mushroom-shaped spacecraft hovering nearby.

Johnson runs to his parents, and they return just in time

to see the craft disappearing in the sky.

But back on the ground, they find this.

Where the UFO allegedly hovered is an eight-foot wide ring

with a whitish crust around the edge.

And take a closer look.

It looks like this ring is glowing.

Harlan Enlow was one of the first law enforcement officers

to arrive on the scene.

- It was a eye opening surprise.

Here's this white, dry ring, looks like a big donut,

sitting in the middle of a mud field.

And we took statements, we photographed it,

and we took actual soil samples.

- [Tony] Ron's mother, Irma Johnson,

tells Harlan she touched the white substance

and instantly, her fingers became numb.

Meanwhile, two other eyewitness reports

of the UFO that night are soon confirmed,

leading Harlan to only one conclusion.

- [Harlan] I am 100% convinced that an incident happened

and what the family told us was credible.

- [Tony] But it doesn't end there.

Journalist MJ Banias says when it comes

to reported UFO landing sites,

these strange sightings are not unique to Kansas.

- We have multiple cases that show UFOs

sort of landing on the ground.

One of the most famous cases was out of the 1980s

in France, in Trans-en-Provence,

where a gentleman was farming in his field

when he saw this large, disc-like object

take off into the sky,

and again, it left impression marks

as to where it was landed,

as well as some burn marks on the ground.

- With a 21-page soil report, the Delphos, Kansas UFO

is considered one of the most lapsed studied UFO cases

in history.

So you'd think if it was possible to explain this ring,

it would've been done by now.

But no dice.

Well, we got our experts here to give it another try.

[tense music]

We begin with astronomer

and video effects designer Marc D'Antonio.

- UFOs have been traditionally associated with heat,

meaning this might have been ash.

But there wasn't an excess of carbon ash

that I could see in the chemical report.

Some of the elements were hydrophobic in nature.

- [Tony] It's that hydrophobicity

that tells physicist Dr. Matthew Szydagis something's up.

- The term hydrophobic means water repellent.

Most soil really needs water.

That's how plants grow.

- [Tony] This photo taken of the Delphos soil sample

about 20 years after the incident

shows a drop of water repelling off it.

So there seems to be something amiss in the soil,

but is it really glowing?

D'Antonio thinks there's an explanation in the camera.

- It looks brighter on the film

precisely because it's a brighter soil

compared to the darker soil,

and the camera tries to balance the light.

- [Tony] But Szydagis says a camera artifact

doesn't explain further research from the soil report.

- We have physical, deposited evidence

that the samples still have the same glowing property today,

which is absolutely mind blowing to me.

- [Tony] For some, the evidence leans alien,

but geologist Dr. Bob Anderson thinks what we're looking at

is natural, a mix of an unknown organism in water

creating a froth of bacteria.

- I realize that this area is pretty conducive

to this kind of thing.

So I don't believe it has anything to do with the UFO.

I think it's a natural phenomena

of groundwater interaction and biology.

It's a gas that's being released by that bacteria.

- [Tony] But what about the numbness

in the mother's hand?

Dr. Anderson thinks he can explain that too.

- The mother got her hand burned a little bit

by touching that ring.

That usually happens if you have an acid.

It wouldn't surprise me if something

got into the groundwater.

My gut feeling is is that there was something buried

in that area that was manmade, chemical,

which would not show up on those 1970 soil surveys.

- [Tony] But still, why the ring shape?

Dr. Szydagis points to another popular theory,

that we're looking at a so-called fairy ring.

They're typically formed by fungus

feeding on decomposing matter in the soil.

The fungus then grows from the center outwards

to form a ring.

- Fairy rings are also known

to have a hydrophobic effect on the soil.

So this does appear to be a partial explanation

that knocks out one or two features

but doesn't seem to fit the entire story.

[tense music]

- From a fairy ring to a possible UFO landing

and even acidic soil,

there were just so many conflicting theories here,

plus all those credible witnesses.

Our verdict is that this is simply

an unexplained phenomenon.

Before you get any ideas to investigate,

you should know that the family eventually buried the ring

to discourage curious trespassers.

But if you ever come across one yourself,

you know who to call.

Emerging 5,000 years ago, ancient Egyptian

is one of the world's oldest writing systems,

consisting of about 1,000 hieroglyphs.

But one recently discovered hieroglyph in particular

feels bizarrely out of place.

In fact, it looks like it belongs right here, right now.

It's April 2009 in Abydos, Egypt.

A French tourist is visiting the Great Temple

built by pharaoh Seti I.

As he wanders through the site,

he photographs something high up on a stone wall

that seems quite out of place.

In the photos, we see a panel in the temple wall

covered with a series of hieroglyphs.

Some seem just like standard characters.

But above those appears a form that looks, to many,

less like something out of ancient Egypt

and more like a modern day helicopter.

And even more remarkable,

beside it are what seemed to be a tank and a spaceship.

- You can see it here with the rotors up top.

You have the back fin here and you have the body here.

Many believers see this as evidence

of an ancient alien intervention.

- [Tony] Journalist Eric Grundhauser

explains there's a concept

known as ancient astronaut theory,

which proposes that some extraterrestrial beings

visited Earth in centuries past.

- [Eric] It sort of created this idea

that aliens helped build the pyramids,

gave us otherworldly technology.

- [Tony] The three Great Pyramids in Giza

are said to align with the stars in Orion's Belt,

which would indicate whoever made them

had advanced astronomical knowledge

and was able to view the site from above.

And Grundhauser says many believe that the appearance

of the other seemingly modern conveyances on the temple wall

gives even more credence to this theory.

- Of course you have the helicopter here,

but then you also have things described by some

to look like a tank or the land speeder from "Star Wars."

- Italian artist and inventor Leonardo da Vinci

made prototype drawings of an ornithopter flying machine

way back in the mid 1500s,

but the first successful helicopters

didn't actually lift off until the 1920s.

So is it possible that the ancient Egyptians

somehow foresaw our technology,

either through their own genius or with alien help,

or could they have actually seen a helicopter-like craft

transported from another galaxy or from the future?

Let's consult the experts.

[tense music]

Archeologist Ed Barnhart examines the photos

to determine if the alien tech theory flies.

- Archeology uses this term called OOPA,

an out of place artifact.

Something that's out of place in the time period

you find it in, are OOPAs,

are these glyphs that really do look like

they're helicopters and spaceships.

- [Tony] Yet, anthropologist Kathy Strain

says the placement of these glyphs

calls the alien theory into question.

- This is the only place that this symbol occurs,

and it's actually up in the corner of the ceiling.

I would expect that if they had really seen a helicopter,

it would be prominent in that temple.

I would also suspect that if they knew

what helicopters were,

they would have them buried in the tombs of the kings.

And there's nothing like that that has ever been found.

Because space in a temple's very valuable.

when one Pharaoh dies and another Pharaoh

comes into power, he likely went into the temple

and erased what was there before and then wrote over it.

And that overwriting caused this illusion

that that symbol is a helicopter.

- [Tony] So it just may be coincidental

for a helicopter to appear in this amalgamation,

which Barnhart concludes is created

with a well-known technique.

- This panel, in its current state, is a palimpsest.

And essentially, you make plaster

out of the same material.

So you can actually shape a new spot

on a flat piece of limestone

to look like the raised hieroglyph that you just erased.

But it doesn't hold through the test of time

so it it falls off and you end up getting things

that look like untranslatable glyphs.

[tense music]

- [Tony] Because of its inconspicuous placement,

its lack of appearance elsewhere in ancient Egypt,

and the experience Barnhart has

with the creation of hieroglyphs,

our verdict is this symbol is an example of a palimpsest.

The original material has been written over,

but traces of it remain.

And over time, the deterioration of the carving

leaves behind an unintended shape that we recognize,

but not the pharaohs.

- Every year, tourists flock to snap photos

of natural wonders like Arizona's Grand Canyon.

But this next amazing marvel is so remote

and potentially dangerous

that it has very rarely been photographed,

much less visited.

And it's been confounding scientists for years.

It's summer 2006 in the Irkutsk Region of Russia.

Geologists Sergey Yazev and Dmitry Semenov

have set out to document their explorations of a remote site

that's baffled scientists to this day.

In their aerial footage, we can see a rock formation

protruding from the surrounding green forest.

The grayish rock looks otherworldly,

completely separate from its surroundings.

It rises 130-feet in the air, with a diameter of 520-feet.

From above, it almost looks like a giant crater.

However, another spherical shape rests inside,

like a volcano with a ball stuck in the center.

Journalist Amy Teitel says the infamous site

is known as the Patomskiy Crater.

- It sort of looks like a crater,

but there's this bolus-looking thing in the middle.

It's unclear how it formed or what exactly it is.

And because it's in a remote location in Siberia,

it's incredibly hard to study.

- [Tony] Teitel says the site was first studied

by Russian scientists in 1949 when the local Yakut people

warned a young geologist about it.

- The local people in the area are the Yakut people,

and they've been aware of this formation for a long time.

It's known as the Fire Eagle's Nest or the Devil Place.

The locals know to avoid this place at all costs.

And they say that anyone who gets too close to it

is immediately overcome with a sense of dread.

One expedition was forced to stop

when its leader died of a sudden heart attack

just three miles from the crater.

- In 2010, the Patomskiy Crater Conference

was held in St. Petersburg, Russia,

where scientists gathered to discuss its origin.

Their results, inconclusive.

So is what we're seeing truly evidence of extraterrestrials?

We have our own team of experts,

so let's see what they can unearth.

[tense music]

NASA geologist Dr. Bob Anderson considers one theory

that's gained some traction,

that the crater could have been created

by two consecutive meteorites.

- We've seen where impacts have hit this area,

especially Siberia.

My problem with the impact idea

is that you don't see an ejecta blanket.

- [Tony] Ejecta blanket is the blanket of debris

surrounding an impact crater.

There is typically a star-shaped distribution of ejecta

around the crater rim because the debris

is ejected up and then out.

There's no ejecta blanket here,

so Anderson is able to rule out meteorites.

Then another theory, could this be a volcano?

- [Bob] The problem is that this

is in a limestone sedimentary rock.

Limestones are developed at the bottom of oceans,

and sedimentary rocks don't form volcanoes.

- [Tony] Siberia is not known for its tectonic activity,

so that makes a volcanic eruption even less likely.

Volcanoes occur most frequently

at the boundaries of tectonic plates,

where the plates are actively moving towards

or away from each other, which isn't happening here.

So could it be a different kind of explosion?

[explosion booming]

Archeologist Dr. Ed Barnhart says that scientists

have detected radiation in the area, leading to theories

about possible undercover military operations.

- When they really started studying it,

it was the Cold War.

So, Americans were very worried

that maybe this was another Russian test site.

The trees around the crater are growing up taller

and had higher levels of uranium

and thorium.

Radiation does make certain plant life

grow bigger and stronger.

So now we have some hint that there is radiation

coming out of here,

but a bomb creates a completely different kind of crater

than we see here.

This crater is compact and it's high.

So it's coming up from the ground.

It's not an explosion that sent things out to the outside.

- [Tony] But Barnhart found a clue.

There's a high level of magnetic activity

in and around this crater.

- [Tony] This could mean that radiation

is naturally coming up from deposits under the earth.

- What we're seeing here likely

is the thorium and uranium that they detected in the trees

decaying under the earth, making an exothermic reaction,

exploding up into this crater.

The exothermic reaction is the same heat

that took the surrounding iron and turned it magnetic.

- [Tony] Anderson believes all this heat

might have caused what's known as a mud volcano,

which differs from the traditional magma volcano

that we've already ruled out.

These natural formations are created

by the eruption of hot water, pressurized gases, and mud

as opposed to lava.

- There have been several mud volcanoes

identified in Greenland,

where you find the sediments on top and they come up.

I've not heard of one being dominated by limestone,

but it's not impossible.

- [Tony] One problem, though.

This theory doesn't explain why this site

instills such fear in the locals

or why the expedition leader suffered a heart attack.

So the true picture remains muddy, for now.

[tense music]

Our verdict, this is an unexplained geological anomaly

that still has us all stumped.

It's possible it was caused by a mud volcano,

but that doesn't explain why the formation

is made out of limestone.

Luckily, we feel like we're in good company

if the greatest minds on Earth are also at a loss.

- Humans have been carving and drawing on rocks

for tens of thousands of years,

but we've never seen anything quite as precise

as this next formation.

Maybe it's a monument, maybe it's a message,

and it's definitely a mystery.

It's October, 2021 near the Tayma Oasis

in northwest Saudi Arabia.

Photographer Satish Javali

is trekking through the remote desert area

to document a magnificent site.

His shots show a monumental rock formation

in the shape of a rounded rectangle.

It appears to be a monadnock,

which is an isolated massive stone.

The 18 by 27-foot ochre-colored slab

is covered in prehistoric petroglyphs of horses, camels,

and hunters shown in stark relief and detail.

But these 4,000 year old drawings

are not the most notable feature of this formation.

That honor is reserved for a perfectly precise crevice

that divides the rock in two.

The crack is so straight and exact

that it seems impossible it could be natural or even manmade

without the most advanced precision tools.

What's even more remarkable is that each half

is balanced precariously on a pedestal,

yet the formation remains standing after millennia.

Satish says he's never seen anything quite like it.

- It is simply mind-blowing the way the rock has been split.

The archeological specialists have gone there,

but nobody has come up with the right answer.

- [Tony] The large, solid boulder looks as though

it was split in half with the aid of a precision laser.

It's hard to believe this perfect crack down the middle

could have been accidental.

So there are a couple of things I wanna show you

with the Al Naslaa rock.

First of all, this pedestal right here,

this pedestal right here.

Built for monuments to rest on, right?

Take a look at the line down the center.

How does this happen?

If you had a stone saw,

could you cut the stone that perfectly?

Again, there are petroglyphs all through this rock.

This rock was created hundreds of thousands of years ago.

And it has certainly spawned wild and amazing stories.

Journalist Eric Grundhauser says one theory

is that the people who drew the glyphs 4,000 years ago

also split the rock.

But did they have advanced enough technology at that time?

- The ancient cultures of the area

were working with much more rudimentary tools

than one would expect to be able to create something

with such precision.

It's almost as if someone would've had to have had a laser

or some sort of highly, highly precision saw

to create this sort of break.

It could have been created possibly

by the Nabataean people,

the same culture that created the Petra site in Jordan,

whose knowledge and expertise

would've possibly been advanced enough

to create something with such precision

as we see in the Al Naslaa formation.

Is it possible that the Al Naslaa formation

was created by extraterrestrials?

Was it left as a gift,

not unlike the monolith from "2001: A Space Odyssey,"

to push humanity forward, to inspire us?

- As early as the fifth century BC,

the Nabataean began carving

elaborate multi-story building facades

into the red sandstone cliff faces of Petra.

But that site is in Jordan,

450 miles away from the Al Naslaa rock,

and it involves more complex carvings

than a single straight line through one rock

in the middle of nowhere.

So that might be a stretch.

Let's see what our experts can dig up.

[tense music]

Physicist Matthew Szydagis investigates

to see if the rock in Al Naslaa

could actually have been made by man or aliens.

- So I've taken an image of the Al Naslaa rock,

and I've actually drawn

two perfectly straight lines from my computer.

And what you can see in several locations

is that actually the rock pokes past the straight lines.

So this gap is actually not perfectly straight.

Humans could create cuts in rocks,

and nearby civilizations here are known to have done that.

No need for ancient aliens.

- [Tony] Since the line isn't actually

as perfectly straight as it looks at first,

perhaps it was made by people from the region.

Archeologist Dr. Ed Barnhart

says nearby ancient civilizations like the Egyptians

had special techniques for cutting into rock

without high tech tools.

- The typical way that Egyptians

would split a stone like this

would be to get up on the top of it

and pick holes into it in a line.

Then as they pecked the holes deep,

they then put wooden stakes inside each one of the holes.

- [Tony] So the Egyptians would put the stakes

in a straight line, like the one seen at Al Naslaa.

- And then they would water those stakes

like you water a plant.

When the wood expanded together as a line of stakes,

they would pull the rock apart.

And that split will travel through the whole stone

and split it.

- [Tony] But geologist Dr. Bob Anderson

says there aren't any telltale signs

of this construction technique that you would expect to see

on the top or sides of the rock if the crack was manmade.

- There's no chip marks, there's no pieces.

You don't even see fragments on the ground around it

that would say if you're chipping and breaking.

I realized that this monadnock, or this isolated rock here,

is not isolated.

There's almost a trail of boulders going back.

They're all cracked at the exact location.

You can see that the crack is a result

of regional tectonic features.

- [Tony] So Anderson believes the rock

may sit on a fault line and it's likely an earthquake

or shifting tectonic plates created the crack,

not just in this boulder,

but in other rocks along the same fault line.

Or it could also be that the crack is a joint,

which in geological terms

means when a rock breaks naturally without displacement.

It's rare, but sometimes the fracture can divide the rock

in an unusually straight line.

Another possibility is that freeze-thaw weathering

may have caused the crack.

But no matter how it was split in two,

Anderson thinks erosion may have played a part

in its near perfect appearance.

- The reason it looks so clearly cut

is because it's been willowed out by the wind.

It's being almost like sandblasted and polished,

which has opened up that crack more.

- [Tony] The ground around and under the boulder

eroded so much that eventually it was left just resting

on these two natural pedestals.

Someday, the forces of gravity

will likely cause it to collapse.

[tense music]

The Al Naslaa rock has baffled scientists for centuries,

but we think we finally found the true answer.

Our verdict?

Tectonic activity created a crack thousands

or even millions of years ago.

It was later perfected with erosion,

which also made those pedestals the rock now rests on.

- We've seen videos of UFOs zigzagging,

tracking commercial aircraft, and even splitting in two,

but this next video is something different.

And if nothing else, it proves that what goes up

does not always come down.

November 2020, on the coast of Cornwall

in southwest England, a live webcam viewer

is recording a gorgeous sunset.

But the footage captures something

more than a postcard-worthy seascape.

A glowing orb races onto screen, hovers,

then rocket straight up and out of frame.

Watch again.

Rapid deceleration and then vertical flight.

It appears to rocket almost 3,000 feet straight up

in less than a second.

Some observers on the internet

alleged it was some kind of alien craft,

but there was another theory.

See how quickly the object rises?

With that kind of speed, is it trying

to not just leave the Earth but also our time period?

- That indicates some sort of space-time distortion.

- [Tony] Anthropologist Michael Masters theorizes

that the passengers in UFO sightings like this

could be us from the future.

- It's important to consider our own evolution

and our technological and biological evolution

in the sense that maybe they're us.

Maybe they're coming from the future

to examine their own hominin evolutionary past.

- [Tony] Masters believes that if future humans

can manipulate time to travel into the past,

they might also be able to build spacecraft

capable of these remarkable maneuvers.

- [Michael] This would also make sense in the context

of what we see in this video,

as this craft flies in at tremendous speed,

and stops instantaneously,

and then accelerates at tremendous speed.

- [Tony] G-force is a measure of acceleration,

with 1 G the force Earth exerts on us.

And at first glance, it looks like G-force

generated by this object's acceleration

would be off the charts.

- I've never seen any device that can stop on a dime

and take off at maximum velocity.

So I would suspect that if this is for real,

it's either an experimental craft by the military

or, let's face it,

possibly an extraterrestrial civilization.

- The forces suggested by this video

pose a technical problem for the time travel theory.

Today's astronauts endure about 3 Gs on liftoff.

At around 6 Gs, the average person can black out.

Past 100 Gs, the forces can shatter bones

and squash our organs.

So if this is a craft transporting humans

from the future, how would they survive?

Is another explanation more plausible?

Let's turn the video over to our experts.

[tense music]

Forensic video analyst Michael Primeau

checks to make sure this video isn't a fake.

- I don't detect any evidence

to support that this has been fabricated

or that this object has been inserted

into the video recording.

I've examined dozens of UFOs and UAPs over the years,

and I have seen some objects that travel

at a high rate of speed.

This is exhibiting similar characteristics.

- [Tony] So the video is legit and the object's rapid movement

is consistent with other UFO sightings,

but that doesn't rule out every existing human technology.

- A leading theory would be a drone.

- [Tony] But Tim McMillan says a secret military drone

wouldn't be out in public.

And regulations for commercial drones

make that explanation unlikely.

- First of all, for commercial drones,

they're capped off at 300-feet for regulation purposes,

so it's hard to get an accurate gauge

on altitude and everything,

but we can see it move through the cloud cover out of frame.

So it definitely appears to be exceeding

that 300-foot maximum that you would expect

with a commercial drone.

This one's unique.

I don't know that I have

a very good explanation for it, frankly.

- [Tony] Astronomer and video effects designer Marc D'Antonio

wonders if the object might be something else entirely,

a reflection.

- If this is a webcam, are we seeing this through a window?

Does that mean there is something

being put on the window,

like a laser pointer, that is moving across the window,

causing this to look this way?

- [Tony] But look at the rest of the frame.

There are no other reflections

suggesting there's a glass window between the camera

and the image it's recording.

- [Marc] I can't tell from this, so I can't come

to any reasonable conclusions.

- [Tony] This one seems to have stumped

just about everyone.

So that leaves Masters' time travel theory.

What does D'Antonio make of it?

- We've already figured out that we

might be able to go faster than the speed of light

by using a warpage of space-time.

And NASA has got a funded lab looking at this

because they think it's a possibility down the line.

- [Tony] And recent research indicates that a worm hole,

another warpage in space-time,

could be used to travel through time.

- You know, sometimes science fiction

does become science fact, and it's a possibility.

[tense music]

- So our verdict?

Well, it's not a hoax, and it's not a plane or a drone,

and it's not a laser pointer.

Until we can identify it conclusively,

we'll consider this a genuine UFO.

But look, we really wanna get to the bottom of this.

If you have any more information about this clip,

please reach out and let us know.

- It is not uncommon to find remains

of deceased animals on a walk in the woods.

What's weird is when those remains

don't look like anything we remember from biology class.

It's January 17th, 2019.

Art student Kohei Kadowaki says he is hiking

through the dense woods near his home

in Chichibu City, Japan when he comes upon a figure

that is totally alien to him.

The footage and photos show what looks like

the skeletal remains of some creature.

But what?

As we zoom in for a closer look,

we can see it has strange, long, twisted talons.

Its spine is severely bent,

with a bone structure that looks almost birdlike.

But then there's the head, which is more square-shaped,

which conjures the image of Hollywood extraterrestrials.

And we see two rows of yellow, humanoid-like teeth.

It's no wonder Kohei was compelled

to post the video online.

- Obviously, one theory about this thing

is that it is not of this world.

There are things about it that are very ET

by way of a giraffe.

It does sort of have the head shape

that a Grey alien might have.

- [Tony] Grey aliens

are the most frequently cited extraterrestrials

in reports of close encounters and abductions,

such as the famous Barney and Betty Hill abduction claim

from 1961.

They described Greys as having small, hairless,

humanoid bodies with large heads and black eyeballs.

These remains fit that description somewhat,

but there are other possibilities as well.

- Maybe this creature is the result of radiation fallout.

Japan was the site of two nuclear detonations

in World War II.

And more recently,

there was the 2011 Fukushima nuclear disaster,

which was rated a number seven

on the international nuclear and radiological event scale,

which was the same as Chernobyl.

- A lot of speculation on this one.

There was even buzz that it was some kind

of biological experiment gone wrong.

The obvious explanation is that it's a hoax.

But Grey alien sightings are always a hot topic,

so we'll give this figure its day in court.

[tense music]

First, we take the footage to anthropologist Kathy Strain,

who has researched accounts of Grey aliens.

So how does this corpse compare?

- When people talk about the Greys,

they usually bring up that there's little ones

and there's big ones.

And the larger ones have very long necks

and they're very skinny.

And this doesn't really look like that

because the proportion with the long neck and the head

isn't correct for it to be one of the taller Greys.

The legs should be much, much longer.

The arms should be much longer.

Everything should be scaled upward in size.

- [Tony] What about the nuclear radiation theory?

- The chances that the skeletons are still out in the wild

is unlikely.

- [Tony] Raccoons eat dead animals,

and they are so prevalent in Japan

their overpopulation is causing a national hubbub.

In the past decade,

the country's raccoon population has tripled.

Strain says any corpse decomposing in the woods

outside Chichibu since the 2011 Fukushima disaster

would've been picked apart by wildlife scavengers.

And she points out something else that bothers her.

- Its eye sockets are too small

to actually have an exterior eyeball.

You may be born without physical exterior eyes,

but you would still have human-sized eye sockets

below the skin.

[baby crying]

- [Tony] Microphthalmia is a phenomenon

on which someone's born with one or two eyes

that are very small.

The eye sockets on this creature are small,

but they appear too tiny

even for a creature with microphthalmia.

Biologist Floyd Hayes is also skeptical

that these remains ever belonged to a living being.

- There are ways in which we could change

the morphology of animal

typically by giving it an extra limb,

or a digit, or even a head.

But to get something to change so dramatically

like the entire head shape

so it's sticking out on both sides or a much longer neck,

that's much more difficult to do.

- [Tony] Hayes is left with one remaining possibility.

- I believe this is a hoax.

- [Tony] Given that none of the theory

seemed to hold up, we tracked down Kohei in Japan.

And when pressed, he admitted the alien corpse

is a project he created for his studies

at Tokyo University of the Arts.

[tense music]

- So mystery solved, this was a clever hoax.

Exciting as it may be to imagine stumbling

upon an alien skeleton during a hike in the woods,

this figure just doesn't cut the mustard.

- Prehistoric cave paintings have been discovered

all around the world.

But deep in the Australian Outback,

we found some images that appear to be so unusual,

some people question if they are from our world at all.

Instead, could they be ancient alien astronauts?

In the Kimberley Region of Western Australia,

the aboriginal people

left intriguing paintings on cave walls.

They are called the Wandjina,

incredible beings Aboriginals said created the world.

incredible beings Aboriginals said created the world.

Take a closer look.

Do you see the round heads and circular eyes?

According to George Haas,

founder of the The Cydonia Institute,

the Wandjina could be out of this world evidence.

- They have radiating feathers that come off the head.

Some believe that when you first look at these,

they scream alien.

And the absence of mouths suggest that possibly,

these extraterrestrials were telepathic.

- [Tony] Wait a minute, did he say aliens?

It's an intriguing theory.

What we do know is that Australian aboriginal culture

goes back 65,000 years and holds that humans were created

by the Wandjina.

These unique paintings are a record of that period,

which they call Dreamtime.

- You don't see these type of images

in other cave paintings done by Neanderthals and early man,

which mostly deal with hunting and animals, deer, bison.

But these paintings that we're seeing in Australia

are totally unique.

- [Tony] In some tales, the Wandjina are referred to

as sky beings or spirits from the clouds

who came down from the Milky Way

and created the Earth and its people.

- Some believe that these portraits of the Wandjina

certainly blur the line between extraterrestrial

and spiritual world.

They seem to have aspects of both.

- When it comes to our origins,

some speculate that ancient extraterrestrial visitors

engineered the creation of modern humans

through DNA manipulation or some other means.

The paintings are intriguing.

Look closely at the lines going across,

creating sections on the body here and here.

Could this be the pattern of an ancient spacesuit?

We asked our experts.

[tense music]

We begin with anthropologist Kathy Strain,

who notes that if the paintings are an elaborate hoax,

then someone must have thought of it over a century ago.

- They were documented by anthropologists

more than a hundred years ago.

And outside the fact that you're adding some paint

to keep the color alive, they haven't changed.

These are not a hoax.

- [Tony] So if the pictures are real, are they of aliens?

We ask archeologist Ed Barnhart.

- There are people who envision

that it's helmets on their heads and suits on their bodies,

but this is a very plodding-looking helmet,

the kind of helmet that you see in 1950s aliens movies.

It's kind of ridiculous to believe

that an advanced civilization came here in suits

that, in our current technology, are archaic.

- [Tony] And the idea that these designs on the bodies

are spacesuits?

- You're gonna see an image like this

and envision suits on their bodies.

But we do see today, in aboriginal ceremonies,

people typically paint their bodies completely white,

their faces, their hair,

and then they'll put some kind of decoration over that.

So I think that it is clearly connected to aboriginal people

who today, paint their bodies in a very similar fashion.

- [Tony] In fact, Kathy Strain sees a clue in one image

that convinces her these are strictly human bodies.

- [Kathy] It is pretty rare to see genitalia

of a male in rock art.

And based on things that witnesses say,

that space aliens don't have genitalia,

that that's not how they reproduce,

these look like human genitalia.

- [Tony] So what are we seeing?

- The halo around the head,

I don't believe that they intended it to be interpreted

as anything other than it's the process of transforming,

and that's your head kind of extending above itself

and continuing to carry out.

- [Tony] The halo has been used

in many different cultures throughout history

to represent spiritual transformation,

including the Aboriginal Australians.

- These images around the heads

are some kind of symbol

of the expansion of their minds and spirits.

[tense music]

- So our verdict, these were likely humans.

In fairness, you do have to ask,

do the aboriginal traditions of body decorations

stem from a time when strange beings were observed?

It's impossible to completely discount.

But if these particular paintings were aliens,

well, then let's just say they were endowed in a human way.

From a UFO landing

to extraterrestrial writing and drawings,

we've unveiled some pretty remarkable evidence.

But one question still remains.

If aliens are attempting to leave evidence behind,

what do they want us to know?

Thank you for watching this special edition

of "The Proof Is Out There."

Please send us any videos, images, or sounds

you think we should investigate.

And remember to keep those cameras rolling.
