ANDREW COLLINS: Everywhere that you look,

there are monuments that the archaeologists had

absolutely no knowledge of whatsoever.

DAVID CHILDRESS: It would seem to be all of the cultures

were trying to signal some kind of sky people.

*

DAVID WILCOCK: What if, when we go past that wall,

the real treasure trove is waiting inside?

GIORGIO TSOUKALOS: With the technology that has been

and is being developed at the moment,

archaeology will have to accept the fact

we have been visited by extraterrestrials

in the remote past.

NARRATOR: Since the dawn of civilization,

mankind has credited its origins to gods

and other visitors from the stars.

What if it were true?

Did extraterrestrial beings

really help to shape our history?

And if so, will new evidence reveal,

once and for all, that we are not alone?

*

NARRATOR: Throughout recorded history,

archaeologists have discovered

new structures, carvings and texts

that have put into question

the established notions of our past.

Ruins dating back thousands of years

reveal engineering skill

surpassing even modern capabilities.

Ancient rock art

depicts figures that resemble astronauts.

And mysterious monoliths aligned with the stars

dot the landscapes of nearly every continent.

In his 1968 book, Chariots of the Gods?,

Erich von Daniken proposed that all of this evidence

pointed to one profound truth,

that extraterrestrials had visited Earth

in the distant past

and changed the course of human history.

*

This concept is known as ancient astronaut theory,

and today it is embraced

by literally millions of people around the world.

Everyone in this room wants to ask,

have you watched Ancient Aliens,

and what's your comment about that series?

REPORTER: King Tut's tomb may have more mysteries to reveal.

The California Institute of Technology published

a study claiming they have discovered

a true ninth planet beyond Pluto.

NARRATOR: Ancient astronaut theorists suggest

the evidence that extraterrestrials visited Earth

is all around us

and say that with new technology,

we are uncovering more proof than ever before.

Liquid water has been found on Mars.

REPORTER 2: NASA's Hubble Space Telescope... have made

independent confirmations in the hunt for extra-solar planets.

REPORTER 3: Gliese 581.

This would be the most Earth-like exoplanet

yet discovered.

In the past few years,

different shafts were discovered in the Great Pyramid.

That was only possible because of our modern technology.

The same thing happens in astronomy.

Because of the Hubble Telescope,

we have discovered more than

two-and-a-half thousand so-called exoplanets,

planets out of our solar system.

The same thing in genetics.

It's all connected.

We should finally understand to link all these things together.

CHILDRESS: With all of the new technologies

that archaeologists have to use now,

ground-penetrating radar, satellite images,

uh, even the access of Google Earth,

has been a tremendous boon to archaeologists,

and they're now finding things that we never thought existed.

WILCOCK: Science ultimately is a belief system

that is based on certain evidence,

but as new evidence comes in,

authentic scientific investigation requires you

to incorporate that evidence

into the model that you are constructing.

If we look at the recent findings,

we're seeing the most revolutionary breakthroughs

in the field of ancient astronaut theory

that we have ever seen.

NARRATOR: Wiltshire, England.

Here stands one of the most mysterious

stone monuments on Earth, Stonehenge.

For centuries, it has baffled archaeologists,

but in September of 2015,

just two miles away,

a discovery was made that could provide

an important new piece to the puzzle.

At the Durrington Walls,

Great Britain's largest ancient henge structure--

or circular earthwork--

archaeologists, using ground-penetrating radar,

uncovered something astonishing,

nearly 100 monolithic standing stones.

Recently, a type of super-henge was discovered

only two miles from Stonehenge,

and it's a giant mystery because,

according to the working archaeologists, it's older.

So the question now is, if it's older than Stonehenge,

what was its purpose, and why was it built?

This is the southern side of Durrington Walls,

the southern edge of the great Superhenge.

And beneath my feet

is at least one and another here

of the 90 great stones.

Now, these stones,

which were perhaps 15 feet in size,

weighing anything between ten and 15 tons apiece,

were part of a huge arc

that faced out towards the northern night sky.

They were constructed as part of a mysterious monument

even earlier than Durrington Walls,

which dates to around 2500 BC.

So they could be hundreds,

perhaps even thousands, of years earlier,

and exactly why it's here is a complete mystery.

DAVID CHEETHAM: These stones were purposely buried,

and they seem to be part of a ritual complex

that goes way beyond that particular site,

into the entire plain on which it's found.

So these stones encircle one part of the site

and were consequently buried under a mound,

which is really mysterious.

NARRATOR: While the stones of Superhenge

that have been discovered so far form an arc,

many researchers believe that it was originally a full circle,

much like another ancient structure

located just 300 yards to the south, Woodhenge.

This is Woodhenge.

This was a smaller monument

consisting of six concentric rings

of wooden posts that pointed up towards the sky

as much as 4,000 years ago.

And this monument itself,

being circular in the same way that Stonehenge was,

suggests to us that the 90 stones

around the edge of Durrington

was a huge great circle in itself,

the largest ring of stones anywhere in Europe,

perhaps even in the world.

NARRATOR: Incredibly, the newly discovered Superhenge

is not all that has been uncovered

beneath the earth here.

Since July 2010,

an international team of experts--

as part of the Stonehenge Hidden Landscapes Project--

has been mapping the entire area using the latest technology.

More than 15 underground sites have been found.

The landscape around Stonehenge

is actually archaeologically very, very rich.

Rather than Stonehenge being this monument

that sits by itself in Salisbury Plain,

what has been revealed is that it is part of

a vast sacred landscape that once

covered Salisbury Plain

and went all the way down to the River Avon.

CHEETHAM: There's no doubt that these finds

will cause English archaeologists to have

to revisit everything we know about Stonehenge,

because Stonehenge is not going to be considered

an isolate or something that's curious.

NARRATOR: While mainstream scientists

believe Stonehenge and its surrounding sites

were ancient ritual and burial grounds,

there is no written record to explain why ancient people

chose to move and erect massive blocks

that weigh up to 50 tons--

some of which were transported from over 100 miles away.

And now that a second Stonehenge has been found,

the theory that these sites were simply burial grounds

has been thrown into greater question.

DAVID WHITEHEAD: These ancient people had a great deal

of knowledge about how to align these structures perfectly.

So, we're dealing with an advanced civilization,

to say the least.

Where they had that knowledge,

where they got that knowledge, where they developed

the ability to put these incredible monuments together,

it boggles the mind.

NARRATOR: Archaeologists believe

that Stonehenge's two rings of standing stones

may be simply the remains of a much larger structure,

based on the presence of the earthen henge

that surrounds it.

This has led to speculation that Superhenge

also contained additional rings,

and that these structures might even have had walls and roofs.

But if true, was this area of England

much more than simply a site of religious ceremony?

WILLIAM HENRY: When we look to these

extraordinary structures on Earth,

it makes you wonder, did extraterrestrials have

a hand in creating these massive monuments?

Or did they teach humans how to build these monuments?

CHILDRESS: So you have to wonder what the purpose of these

giant stone circles are around the world.

Is it possible that they were some

kind of spaceport or a conceived city?

NARRATOR: Is it possible that Stonehenge

and the many structures that surround it

are the remnants of an extraterrestrial spaceport?

Ancient astronaut theorists say yes,

and suggest that further proof exists

in the form of DNA evidence,

hidden in the tomb

of King Tut.

RAMY ROMANY: They have confi NARRATOR: Luxor, Egypt.

Here lies the tomb of the world's most famous pharaoh...

King Tutankhamun.

When it was discovered in 1922,

completely intact and preserved

after more than 3,000 years,

it was considered one of the most significant

archaeological discoveries of all time.

But as spectacular a find as it was,

almost a century later,

new evidence has come to light that there may be much more

to King Tut's final resting place than meets the eye.

While examining high-resolution scans of the tomb

on September 28, 2015,

British Egyptologist Nicholas Reeves

found something remarkable--

the possibility of two hidden passages

connected directly to King Tut's burial chamber.

ROBERT BAUVAL: There was a Spanish company,

who was recruited to scan the tomb of Tutankhamun

in order to replicate it.

It is through this high definition photography scanning

that Reeves noticed that on the north wall

of the burial chamber, there is some cracks,

indicating the possibility of a door.

And also on the eastern wall.

So there's two possible chambers.

ROMANY: Reeves took his laser images to Dr. Mamdouh Eldamaty,

who is the Minister of Antiquities in Egypt,

and they both decided to dig further.

They used thermal scanning, which tells you

the exact density of the wall at every part.

And they have confirmed that they might have discovered

another passway or a chamber

behind King Tut's burial chamber.

NARRATOR: Whether there are more buried treasures

beyond the painted walls remains to be seen.

But if so, Reeves has a theory.

He believes the passageway may lead

to the tomb of Queen Nefertiti--

the wife of Pharaoh Akhenaten,

who ruled during the 14th century BC.

BAUVAL: Reeves speculates that, in fact, Tutankhamun

inherited the tomb of Nefertiti.

The reason is this-- the tomb of Tutankhamun is very unusual.

It's rather small compared to the other pharaohs.

All great kings of the 18th Dynasty have

amazingly large tombs with storerooms

and chambers and so forth.

Tutankhamun's tomb-- if it is his tomb--

is very modest.

NARRATOR: But why would Nefertiti's tomb

be hidden beyond King Tut's?

Ancient astronaut theorists believe there may be

a profound reason--

that Queen Nefertiti

was not of this world.

Nefertiti's parents are unknown.

On pictures, she is shown

with one of these elongated heads.

Now we know the gods,

the old Egyptian gods,

they had longer heads than we have.

And according to the pyramid texts,

sometimes they left the Earth,

and then they returned again.

So Nefertiti's parents were maybe extraterrestrials.

ROMANY: King Akhenaten and his wife

looked completely different

than all the other ancient Egyptian kings.

King Akhenaten always was depicted

with an elongated skull, a bigger-size hip,

a belly that drools over his belt.

He believed that he wasn't a man

and he wasn't a woman and he wasn't a king.

He was just something else.

BAUVAL: The most unusual feature is, uh, elongated skulls.

There's been a lot of discussions

about what these skulls meant.

Whether they were literally elongated skulls,

or whether they were just decoration features.

It's certainly very intriguing.

It doesn't appear before or afterwards.

So there's something rather odd about this, I have to admit.

NARRATOR: The reign of Akhenaten and Nefertiti

introduced a new and controversial

monotheistic faith to Egypt--

worshipping the disc-shaped sun god Aten.

TSOUKALOS: The Aten was described

as this flying sun disc.

Egyptologists are

merely saying that this was nothing else but the sun,

but the question is:

Can the sun instruct you in different disciplines?

And the answer is no.

So we have to see whether or not

our ancestors encountered technology

and misinterpreted it as something in nature.

NARRATOR: Is it possible the depictions

of Akhenaten and Nefertiti--

along with their worship of a disc-shaped god--

are evidence that they were not of this world?

And if so, might Queen Nefertiti's tomb

contain DNA evidence of

their extraterrestrial origins?

The ancient Egyptians did not want us

to know anything about Nefertiti or Akhenaten,

or even Tutankhamen.

They made every effort they possibly could

to erase all references to their existence.

So what is it about Nefertiti

that makes the opening of her tomb so powerful?

This ultimately goes back to Akhenaten

and Nefertiti's introduction of the teaching

of the celestial disc.

What if, when we go past that wall,

the real treasure trove is waiting inside,

and when we go in there, we're going to find artifacts

that could be undeniably extraterrestrial?

NARRATOR: Could this tomb hide

otherworldly secrets and treasures?

Might we be on the verge

of locating indisputable evidence

of extraterrestrial intervention

in the distant past?

Perhaps additional pieces to the puzzle

can be found deep within the temple

of a flying serpent god.

NARRATOR: Teotihuacan, Mexico.

April 24, 2015.

For six years,

Mexican archaeologist Sergio Gómez

has been performing an excavation

of the ancient city's third largest pyramid,

the Pyramid of Quetzalcoatl,

which dates back to the second century AD.

Gómez has uncovered numerous relics

in the course of his excavation,

but on this date, he discovers something completely unexpected

in a chamber below the pyramid:

Large quantities of liquid mercury.

COLLINS: Gómez has been gradually penetrating a tunnel

and he's now reached

a depth of 300 feet.

But along the way, they found liquid mercury.

Now, why would you put

liquid mercury inside a tomb?

GEORGE NOORY: You wouldn't want to put mercury down there

just for the heck of it,

because if you get too close to it,

or too involved with it, it's gonna kill you.

NARRATOR: Mercury is an extremely rare

and conductive element that, today, is used primarily

in electronics and automobiles,

so the presence of this dangerous substance

below an ancient Aztec pyramid

has puzzled scientists.

But ancient astronaut theorists believe

the mercury found at this temple--

a temple built to honor Quetzalcoatl,

the feathered serpent that came down from the sky--

may have a direct connection

to the beings the Aztecs referred to as their gods.

Now, liquid mercury

was not only found in Teotihuacan.

According to old Indian texts,

liquid mercury was one part

of the propulsion system

which the extraterrestrials used

for their flying machines.

WILCOCK: There are many legends that the Nazis themselves

actually went through these Sanskrit texts

in order to help them develop

their own flying craft technology.

What we know from the leaked German scientific reports

is that, apparently, if you subject mercury

to a very high level of electrostatic charge

and then rotate it,

you get a gravitational thrust

which allows you to create inertial force

that can counteract the normal force of gravity.

TSOUKALOS: So the idea that we have references to mercury

in a chamber of the Feathered Serpent...

One has to ask the question:

what was this Feathered Serpent?

According to the ancient astronaut theory,

we are talking about physical craft

that, at some point,

were misinterpreted as living creatures.

NARRATOR: Could this incredible discovery of liquid mercury

provide further proof

that the Feathered Serpent was actually a spacecraft?

Ancient astronaut theorists believe another toxic tomb

may help answer this question.

Shaanxi Province, China.

Here, buried deep under a hill,

lies Emperor Qin Shi Huang.

Undisturbed for more than 2,000 years,

his tomb is best known

for the discovery of thousands of Terra-cotta Warriors.

But much of the massive underground structure

has not yet been excavated,

due to high levels of mercury.

If somebody were to ask me,

"What is the most fantastic archaeological site

on the planet Earth?",

my answer would be simple and it would be quick:

it's the tomb of Emperor Qin.

Writings from the time of Emperor Qin,

second century BC,

told us that this guy was buried in a tomb

that had a scale model of China inside of it,

with flowing rivers of mercury moving around the cities

that were built in scale models.

NARRATOR: Is it coincidence that an ancient tomb in China

and an ancient temple in Mexico

both contain liquid mercury?

Curiously, much like the Aztec story

of Quetzalcoatl coming down from the sky,

the Chinese say the ancestor of Qin Shi Huang--

the Yellow Emperor--

descended from the heavens on a dragon.

According to some mythological accounts,

the Yellow Emperor was riding around on a dragon

when he saw the people of Earth in need.

And so he descended from the heavens to help them.

NARRATOR: According to Chinese myth,

after ruling for 100 years,

the Yellow Emperor called for the return of the dragon.

WILCOCK: 70 different people from his own staff

all got on board this dragon and flew away.

The dragon is said to travel vast distances

in short periods of time.

So the yellow dragon does appear to be

a very large spacecraft,

traveling at extraordinary speed,

and all of the events that I'm describing to you

actually did take place in physical, tangible reality.

Liquid mercury is such an obscure substance.

So how do we account for both the ancient Aztecs

and the Chinese creating rivers of mercury

in the tombs of some of their greatest figures,

unless they know the hidden secrets of the substance,

hidden secrets that were taught to them by extraterrestrials?

NARRATOR: Is it possible that the Aztec story

of a flying feathered serpent

and the Chinese story

of a dragon coming down from the sky

are both describing alien spacecraft?

And is this why liquid mercury

has been found in tombs both in Mexico and China?

Ancient astronaut theorists say yes,

and propose even more compelling evidence

that our ancestors encountered otherworldly technology

might lie high in the mountains of Peru,

hidden beneath the earth.

NARRATOR: Machu Picchu, Peru.

This stone citadel of the Inca civilization

was built high in the Andes Mountains

around 1450 AD,

but was suddenly and mysteriously abandoned

roughly a century later.

Mainstream scholars contend

the construction of Machu Picchu

was led by Emperor Pachacutec

and took thousands of men

working decades to complete.

But ancient astronaut theorists suggest

that the precise construction,

the transportation of massive blocks

and the Incas' own accounts

all point to a very different

explanation for Machu Picchu:

That it was built with the help

of otherworldly beings.

Emperor Pachacutec was believed to have had

a special bond with the god Viracocha.

ED BARNHART: Pachacutec, in the days leading up

to the great battle against the Chanka,

he takes kind of a retreat.

He goes to a lake.

And out of the sky drops this piece of metal

into the lake.

When he fishes it out of the lake, it's a mirror.

And he sees an image in the mirror.

This supernatural creature in the mirror tells him,

"I am your father.

"You will win many battles in your lifetime,

this one included."

The image is actually Viracocha, the creator deity.

And then as Pachacutec stood

with his vastly smaller army,

these giant megalithic stones came to life

and became his army, and crushed the Chanka.

Pachacutec actually had the power of Viracocha behind him.

It makes one wonder

if, in fact, this was extraterrestrial technology.

NARRATOR: Could the story

of Pachacutec levitating massive stones be true?

And might the mirror that fell from the sky

have been some type of alien technology?

Ancient astronaut theorists say yes

and suggest a new discovery at Machu Picchu may reveal

what happened to this otherworldly device.

*

French engineer David Crespy was vacationing

in Machu Picchu in 2010, when he discovered

that at the bottom of one of the main buildings,

there seemed to be a doorway,

purposely sealed up with rocks.

In August of 2011, he reached out

to Thierry Jamin, a French archaeologist

that has been studying Peru and the Incan Empire

for more than 15 years.

Within a month,

Thierry started his own investigation

with local archaeologists and specialists in funerary sites.

Thierry and radar technician Ricardo Hamada

took a scan from above the blocked entrance

with ground-penetrating radar.

The image on the radar detector reveals a large cavity,

and the broken lines indicate there may also be stairs

leading even further down into the earth.

Other equipment detected

that there was metals inside this hidden chamber.

Gold, silver,

and other types of metallic objects,

suggesting very strongly

that we're dealing with some kind of a tomb.

NARRATOR: Although Thierry has confirmed Crespy's suspicions

that the odd structure was an entrance

sealed off at some point by the Incas,

the Peruvian authorities have since banned his return

to the site for further investigations.

(Thierry Jamin speaking Spanish)

TRANSLATOR: All of the iconographic

and archaeological elements show us

that this is all associated

with the mausoleum of Pachacutec.

Maybe the most important archaeological treasure

ever found in Machu Picchu.

NARRATOR: Could the tomb of Pachacutec

lie beyond these rocks?

And is it possible, as ancient astronaut theorists suggest,

that it might also contain advanced technology,

the so-called "magic mirror" that was said to have been given

to Pachacutec by the creator god Viracocha?

HENRY: We're talking about the emperor as having

a connection with this extraterrestrial being.

Now think about it.

If-if we're talking about recovering

his tomb and his artifacts,

then we're talking about ultimately being able

to recover the power that Pachacutec possessed.

And what we're going to be seeing here is, I believe,

ironclad evidence emerging

of extraterrestrial involvement in human affairs.

NARRATOR: When the underground chamber

found at Machu Picchu is excavated,

will we discover undeniable proof

that this site was constructed

with extraterrestrial technology?

Ancient astronaut theorists suggest

further evidence can be found

by examining newly discovered Nazca Lines

as well as similar geoglyphs

found on the other side of the world.

NARRATOR: Nazca, Peru.

First discovered in 1927,

the Nazca Lines consist

of hundreds of designs known as geoglyphs,

that can only be seen from above.

Scattered over 200 square miles

in southern Peru,

mainstream archaeologists believe the figures were created

by the ancient Nazca people

sometime between the first and eighth centuries AD.

Ancient astronaut theorists

have been studying the Nazca Lines for years.

They maintain that the massive and complex designs

must have been created as signals to celestial beings

that came down from the heavens,

and they say new evidence proves

that aliens not only visited Nazca,

but continued to return there over the centuries.

On July 7, 2015,

a team of anthropologists from Yamagata University in Japan

revealed they had found new Nazca lines

that, due to erosion, are impossible to make out

with the naked eye.

By conducting

a three-dimensional scan of the ground,

they uncovered a total of 24 images,

including strange-looking humanoid figures,

a disembodied head and a llama 65 feet long.

According to their findings,

the new geoglyphs date from 400 to 200 BC,

making them hundreds of years older

than those previously discovered.

These new finds are instrumental in showing

the duration of which these types of modifications

were going on, on the desert floor,

for hundreds and hundreds of years,

involving different cultures,

with different motivations and different depictions.

It would seem to be all of the cultures

were trying to signal some kind of sky people

and probably, over time, were trying

to induce them to come back down from the sky

and land their ships.

You have to wonder then if,

with at least four successive cultures doing this,

that you would think they must have had some success.

NARRATOR: Some ancient astronaut theorists have even suggested

that the discovery of older Nazca lines may indicate

that the people responsible for the later geoglyphs

were imitating what was originally made

by the extraterrestrials themselves.

JASON MARTELL: So the question starts to rise is:

were various different people coming to Nazca

to make these petroglyphs and these large diagrams?

Or were they possibly recreating some initial experiment

or some initial thing that took place?

What if some of the early cultures in Nazca

actually experienced interaction with beings

that were creating edifices that can only be seen from the sky,

and the only way to get to lure them back

was to create these ways to communicate

from an aerial perspective?

NARRATOR: For decades, it was thought

that there was no other place on Earth like Nazca,

but recently, a shocking discovery was made

on the opposite side of the globe.

NARRATOR: Turgay, Kazakhstan.

October, 2015.

Using satellite photography,

NASA captures images

of more than 260 geoglyphs

covering the ground here.

They're located in a very rural part of Kazakhstan

and they could only be found thanks to modern technology.

They are much more complex than the Nazca geoglyphs

in that they are three-dimensional.

They are mounds and trenches,

whereas the Nazca Lines

are etchings in the sand.

COLLINS: We're talking here

about massive features

that are constructed from earthen mounds

and also from wood,

showing everything from rings, to squares,

to crosses and even swastikas that are on the ground.

NARRATOR: The archaeologists in the area have no idea

who made the geoglyphs or what they represent.

But one fact they have been able to determine

is that some of these glyphs date back 8,000 years--

nearly 6,000 years older

than the Nazca lines.

Since these can be dated to almost 8,000 years old,

we have to wonder who they were trying to communicate with.

Could it have been, possibly,

what a lot of these ancient cultures referred to as gods?

I think the fact that we're finding

more and more of these symbols

simply tell us that the humankind, at that time,

tried to communicate with

what they thought were the gods from above.

NARRATOR: Could the new geoglyphs

found in Kazakhstan

be evidence that our ancestors encountered

extraterrestrial visitors as much as 8,000 years ago?

Ancient astronaut theorists say yes,

and suggest that these glyphs may prove to have been made

at the same time as the newly discovered Superhenge...

...because, while Stonehenge is considered to be

at least 5,000 years old,

some believe the buried monoliths of Superhenge

could be much, much older.

Stonehenge is only one small part

of a gigantic archeological puzzle.

Now, we, today,

we must stumble over these stone circles,

over these stone lines.

And automatically, we have to ask questions:

What is it?

How have they done it?

For what purpose?

And sooner or later, we came up with the question:

Is there maybe a message by the extraterrestrials?

NARRATOR: Is it possible

that the geoglyphs recently discovered

in Nazca and Kazakhstan

are tied to not only

the new discovery of Superhenge in England,

but also to other mysterious sites around the world

that were made to be seen from the sky?

If so, could evidence that these markers

were intended for extraterrestrial visitors

be hidden beneath the earth

in Mexico, Peru, China and Egypt?

Ancient astronaut theorists say yes,

and suggest that we are on the verge

of uncovering the ultimate proof of alien contact.

(electronic blipping)

NARRATOR: Ancient astronaut theorists argue

that in recent times, the mainstream

has dismissed the possibility

that another race of advanced beings

came to Earth in the distant past,

even though the signs are all around us.

ELLIOT HILL: Experts believe a series of mysterious objects

surrounding a giant star

could be, Mark, an alien megastructure.

1,500 light years from Earth,

signals are blasting

from the star KIC-84-62-85-2.

It could be a... giant solar panels

built by an alien civilization.

REPORTER: Thousands of miles away

in a cave in South Africa, archaeologists discovered

hundreds of ancient bones and a new human ancestor.

NARRATOR: As more and more new evidence pours in,

is ancient astronaut theory nearing a point

where it will be considered by mainstream scholars

as a serious possibility?

Great thinkers like Galileo

are dismissed as fools and heretics.

They were the ones that had the right idea,

but new ideas are not accepted easily.

For centuries, it was believed

that the Earth was flat.

We are a stubborn people.

NOORY: As we evolve as a humankind,

we are going to realize that what we were taught in the past

may not be what is going to be in the future.

We're gonna continue to learn

new things about past civilizations,

and new things of what could've been

future civilizations, as well.

And you've got to conclude

that we are not alone in the universe,

and that we've been visited,

and we continue to be visited.

With the technology that has been

and is being developed at the moment,

ultimately, archaeology will have no other choice

but to accept the fact

that we have been visited by extraterrestrials

in the remote past.

For me, personally, I think that these extraterrestrials,

they left a purpose.

I call it something like a time capsule.

That's why they made

these gigantic stone circles and stone lines.

It was addressed to us.

And we should ask, who were these extraterrestrials?

Where did they come from?

What was the reason?

Will they come down again?

I'm sure they will show up.

We are now living in a paradigm shift

in which the new evidence is upholding

an older and ancient idea

that extraterrestrials came to Earth

and had a huge influence on human affairs.

And that ultimately, our future depends

on our involvement with these beings, as well.

NARRATOR: As technology continues to improve,

will irrefutable evidence be uncovered

of extraterrestrial intervention on Earth?

Evidence that world governments

have been hiding from us for decades?

Could the smoking gun be concealed

behind a tomb wall,

hidden away in an ancient temple,

or even buried right under our feet?

If otherworldly beings really have been observing us,

perhaps as we get closer to the truth,

the proof will come not in the form of an artifact

or scientific discovery,

but in face-to-face contact

with our alien ancestors.
