- Tonight on "the proof is out there."

What is hiding beneath th

of the world's deepest lake?

- There is undoubtedly animal life down there

that has yet to be found.

- [Tony] Did these famous recordings

really capture the sound of bigfoot?

[Creature growling]

And is that a dinosaur running wild in Florida?

- My immediate thought is it's a raptor.

Around the globe are videos-

- [woman] What the heck is this?

- [Tony] Photos and sounds that defy explanation.

- [Man] Is it some kind of unidentified object?

- [Man 2] A plane that was literally frozen in the air.

- [Tony] What are they?

- [Man 3] Some sort of bizarre mutation.

- Extraordinary claims need extraordinary proof.

- I'm Tony Harris.

And as a journalist for more than 30 years,

I've followed the facts where they take me.

Now I'm bringing that spirit of investigation

to the world's strangest sounds and images.

[Creature growling]

We'll analyze each one with top experts.

- It's a credible case, it's a credible video.

- [Tony] And pass a verdict on what it is.

- This video was clearly faked.

- The proof starts now.

[Dramatic music]

Hello, everybody, and welcome to "the proof is out there."

Lake baikal in Siberia, Russia is the oldest,

deepest, freshwater lake on earth.

Over a mile deep, it holds 1/5 of the planet's fresh water.

But is there proof it could also be holding

a species not of this earth?

Take a look.

[Slow dramatic music]

One night in 2015, a group of veteran fishermen

is out on a routine trip,

when they come across something they cannot explain.

A camera on board captures a strange bright

blue-green light glowing just below the surface of the lake.

As you can see, when the camera zooms out,

the light stays put in the choppy waters

as the ship heads back to shore.

Locals have long believed strange things

were happening below the surface here.

- Lake baikal is a hotbed of ufo activity.

So if there's beings coming from a different planet,

we would expect that they might want

to set up a base here on earth.

So a place like lake baikal could be a very good location.

- [Tony] Journalist mj banias

recalls one reported encounter in the lake

that lends credence to this theory.

- There's a strange story that comes out

of lake baikal in 1982.

Russian divers were operating under the water

when all of a sudden they bumped into

these strange creatures.

According to the story,

these creatures were wearing silvery suits.

They were humanoid in appearance.

The divers were so shocked by what they saw

that they tried to quickly leave the area.

And three died due to coming up too quickly

from the depths of lake baikal.

[Slow dramatic music]

- [Tony] This blue light has never been seen again.

So who or what created it?

- There is undoubtedly animal life down there

that has yet to be found.

Whether that animal life is alien in nature,

that is still in the realm of speculation.

- 2/3 of the 2,000 planted animal species

living around lake baikal

can't be found anywhere else in the world.

So it's already a unique place.

But does this video indicate

there are extraterrestrial beings camping out there too?

Let's let our experts have their say.

[Slow dramatic music]

First we have video forensic analyst, Michael primeau,

check whether the light could have been

digitally inserted in the footage.

- It doesn't appear to be cgi.

It doesn't look like something

that was added after the fact.

- [Tony] It's possible then that we're just looking

at a searchlight from another unseen boat or an aircraft,

based on how light should act on a lake such as this,

but physics professor michio kaku

throws cold water on that idea.

- The surface ripples in all directions.

Some of the light would have been reflected

in different angles, but we see no evidence

of an external light source.

- [Tony] An external light source

would fan across the water like this.

But we see nothing like that here.

That also rules out the reflection of the moon.

So if it's something under the lake,

marine biologist, shea conger examines

if it could be coming from a man-made underwater vessel.

- You wouldn't have an artificial light on

during the night if you wanted to study animals

in their natural environment.

So it seems pretty unlikely

this is some sort of a research vehicle.

- It's well-known that bioluminescent

marine life glows at night.

But conger doubts that's what is happening here either.

- We don't actually have

any bioluminescent animals in lake baikal.

It's a freshwater body of water.

In addition, bioluminescent animals

tend to act in kind of a flashy manner.

We would see a flash of light and then it would dissipate.

This is a solid light source.

So I can actually rule out the fact

that it might be some type of animal.

I conclude that this is some sort of underwater technology

that's really difficult to understand or make sense of.

[Slow dramatic music]

- Our verdict?

This is still an unexplained phenomenon.

We can't say for sure whether or not

it's from something extraterrestrial.

But two years after this incident,

a mysterious mass death of seals in the lake

also baffled researchers.

So something fishy is definitely happening.

We'll keep an eye on it.

[Dramatic music]

And ask someone what bigfoot looks like,

you'd get similar answers most every time.

But what if you asked what bigfoot sounds like.

This recording might be the answer.

[Birds chirping]

This story goes all the way back to California in 1971.

Al Berry and his friend Ron morehead

have come to the Sierra Nevada mountains

to investigate mysterious noises

reported by a bewildered group of hunters.

What their microphone picks up at night

becomes the first of a series of recordings

now known as the Sierra sounds.

[Creature growling]

The recordings capture a series of guttural grunts, howls,

and growls thought to be made by an alleged bigfoot.

- The very first sounds were very aggressive,

could be considered very scary.

But again, they weren't coming after us.

So we don't know the intent.

We don't know their agenda.

We don't know what it was.

- [Tony] Ron claims that later he even interacted

with these mysterious creatures

before getting his first glimpse of one.

[Creature calling] [Ron calling]

- I was responding back to them.

And that was probably the most unique

bigfoot encounter I've ever had.

- Field researcher cliff barackman says the Sierra sounds

are the gold standard of bigfoot vocalizations.

- I've spoken to several witnesses

that have recorded this kind of sound.

That says something about the authenticity

of not only their sighting, but these sounds.

- [Tony] The recordings range from guttural growls,

[creature growling]

To wild whoops.

[Creature whooping]

To something that almost sounds like language.

[Creature chattering]

- There's a retired crypto linguist from the us Navy.

He's realized that there are phonemic patterns

that repeat in the sounds.

Those are words.

Sasquatches might be talking to one another.

- Now here's the thing about bigfoot sounds.

[Creature growling]

They're easy to fake and easier to misidentify.

We've heard examples of both.

So let's dial things down a bit

and check in with our experts.

[Slow music]

Zoologist roxy furman notes that there

are no known primates in California.

But whatever made these sounds is big.

- The sound is really loud

and it's quite a low pitch and frequency, so it travels far.

So it's likely that it came from a large animal.

- [Tony] Next, we bring the recordings

to soundscape ecologist, Dr. Ben gottesman.

- So here we have three phrases.

- [Tony] First gottesman examines the guttural sound.

[Creature growling]

Next the whooping.

- The second has these low to high up sweeps.

[Creature whooping]

[Ben whooping]

- [Tony] And finally the chatter.

[Creature chattering]

- And those almost sound like words.

- [Tony] The question, could those come

from any known large animals native to the area?

- We're now going to listen to the sound of an elk bugling.

[Elk bugling]

[Creature growling]

[Creature whooping]

[Creature chattering]

The sound of an elk bugling has much longer tonal signals.

This is not a match.

Now let's listen to the sounds of a black bear.

[Bear growling]

[Creature growling]

[Creature whooping]

[Creature chattering]

While the frequency range is similar,

the shape and complexity of the signals

are totally different.

The Sierra sounds are on a much more advanced level.

- [Tony] Gottesman also rules out an assortment

of smaller creatures, since they lack lung capacity

to create calls that loud and low.

[Slow dramatic music]

Gottesman also notices that whatever made these sounds

has an enormous vocal range.

- If this is produced by a single creature,

there's just a remarkable acoustic diversity

that this alleged species has.

If they are an animal, I can't confidently point to one,

especially one that's native to North America.

- [Tony] So could the sounds have been made by other humans?

- I do not believe that it is possible for this to be human,

because it has a great variance

of going to very high pitched

down to a very low growl, all within seconds.

[Creature growling]

[Creature whooping]

[Creature chattering]

We're not capable of that

without blowing out our vocal cords.

My conclusion is that they are real recordings of bigfoot.

And I base that on knowing how remote that location was

and the impossibility for another human

or other thing to have made those sounds.

- The Sierra sounds recordings are legitimate.

Scientists and even some linguists point to them

as evidence multiple bigfoots

were communicating with each other,

as well as with morehead and Berry.

Our verdict here?

Unidentified animal sounds.

Regardless of what made them,

the bigfoot legend continues to speak to us.

The big question is, are we really listening?

[Dramatic music]

A ufo over north Carolina that appeared to subdivide,

not once, but twice.

Our experts couldn't agree what that was.

And now we've got another challenge for them,

a similar phenomenon in a different place.

[Slow dramatic music]

Warminster, england, about 100 miles west of London.

The passenger in a parked car notices something

that appears to be a couple of helicopters or drones.

But then look at this.

They seem to split into five or six smaller objects

and then perform a series of coordinated maneuvers.

And it isn't the only video like this coming out of england.

Almost 300 miles away in sunderland,

a beachgoer catches this on camera.

Here two bright orbs loop across the sky and seem to divide.

It looks kind of like fireworks at first, but then watch.

The split orbs proceed to conduct

similar coordinated maneuvers,

just like the warminster video.

They remind journalist and author Alexis Brooks

of other firsthand accounts.

- In the field of ufology there is something,

in fact, called ufo mitosis.

Objects that are seen first as one

and then replicating themselves

and following a similar trajectory.

This could be what we're seeing.

- [Tony] And taking it one step further,

Brooks wonders if the ufos splitting

is part of an actual biological process.

- I've spoken to quite a few individuals

who have been taken on board craft

that believe the craft is actually alive.

Not just the occupants of the craft, but the craft itself.

The assumption is that the craft

may in fact be sentient as well.

- During world war ii, Winston Churchill

suppressed reports of a ufo sighting

in order to avoid widespread panic.

Could the splitting ufos be similar to what he feared?

We turn to our experts for answers.

[Slow dramatic music]

Military analyst Tim mcmillan

looks at the sunderland footage

and eliminates some possible explanations.

[Fireworks crackling]

- It's not consistent with any fireworks

that I'm familiar with, mainly because

it's doing barrel rolls,

it's leaving a lot of showering sparks.

- [Tony] Mcmillan also thinks that no secret weapon

would be tested or operated over a public beach

out in the open like this.

- It's doing a pretty impressive show

that would lead me to believe

that we're not looking at classified military technology.

- [Tony] He also thinks he can rule out ufos,

if only because of those odd sparks.

- [Tim] I'm unfamiliar with anybody who has seen

any ufos showering sparks and doing barrel rolls.

- [Tony] In recent years, China has used

elaborate drone swarms to create synchronized displays.

Could this be something similar?

- Potentially a drone-type system

that is specifically designed

to provide a fireworks display,

that's able to shower sparks, and do barrel rolls,

and travel all throughout the sky like this.

- So it's possible.

But instead of focusing just on the objects,

astronomer and video effects designer Marc d'Antonio

looks at these people on the beach.

- I see what appears to be people looking at this.

This person looks like he's looking some other direction.

That would be a pretty eye-catching thing.

Here's people that are bent over doing other things.

And that this is happening without anyone

really paying attention to it,

that is sort of a bit of a red flag for me.

- [Tony] And if this video is sort

of a red flag for d'Antonio, the warminster video

raises that flag and gives it a good wave.

- Now coming out from behind the hill,

look, they're suddenly there.

So watch. Boom.

They started out here.

The transition out of the hill is missing.

It was removed from the video, probably because

the person who is creating this put in his little dots

and took those frames out because he couldn't

get a convincing exit from the hill.

I think I have to label this one a hoax.

[Slow music]

- One more thing about the warminster video.

Just about every time the orbs get close to the hill,

everything goes blurry.

You see this?

Like there's something to hide.

There is no point in splitting hairs

over self splitting ufos.

We're concluding that both videos

are in fact cgi creations.

Gotcha.

[Dramatic music]

More than 65 million years ago.

But what if they still exist

and are running wild in our neighborhoods?

Sounds wacky, I know, until you watch this.

[Gentle music]

April 2021.

Christina Ryan is asleep in her home in palm beach, Florida.

But while her eyes are shut, her home security camera

is wide awake, and it captures this wild footage.

[Dramatic music]

The video, just four seconds long, shows an animal

running across the front yard in the dead of night.

Let's slow it down and take another look.

It's hard to tell exactly what this is,

but there is no doubt in Christina's mind

about what her camera recorded.

- My immediate thought is it's a raptor

or some type of a dinosaur.

The way that it's running and just the entire shape

and everything indicated to me, dinosaur.

- [Tony] Field researcher Ken gerhard agrees.

The blurry, but extremely intriguing clip

screams velociraptor to him too.

- It appears to have a kind of a long

and powerful sturdy tail.

This is kind of the classic image

of a small bipedal theropod type of dinosaur.

- [Tony] As crazy as it may seem,

gerhard shares that there are many modern day accounts

of living dinosaurs, just like Christina Ryan's,

right here in the us of a.

- In southwest Colorado there have been many sightings,

and they're referred to as river dinosaurs or river lizards.

These are basically smaller types

of theropod-like dinosaurs,

just like we're seeing in the Florida video.

- There are also traditions in southwest Texas

of tall bipedal lizards called mountain boomers,

larger versions of a known smaller species.

These sightings are fleeting, but they do happen.

So is it that crazy to think that other dinosaur species

could be alive and well in Florida?

Let's ask our experts.

[Slow dramatic music]

- Because it's moving at a high rate of speed

and the encoder is not set to capture that information

with a high quality, it's essentially blurring

and elongating some of that

with motion trail compression artifacting.

The pixel information that was captured

was not captured with accuracy.

- [Tony] So primeau says the footage hasn't been altered,

but it still may be distorted in the camera.

The tail of this creature may not be what it seems.

So we brought in our residents zoologist roxy furman,

who reminds us where this happened

and why that may be a clue.

- Florida is famous for its exotic pet trade.

And also they obviously have gators in the region.

The way it moves could be reptile-like.

It moves kind of side to side in a this waddle-like manner.

But its body pattern has no indication of scales

or any different coloration or variation along the back.

So for me, that kind of rules out any kind of reptile.

- [Tony] That would eliminate

giant prehistoric reptiles like raptors too.

So if it isn't a dinosaur, then what is it?

- What I think is most likely is a dog that's got loose.

You can see the tail running behind it.

- [Tony] The tail looks like a lizard's

due to the picture distortion primeau identified.

- And it also looks like there's something

kind of dragging like a leash.

And that would also explain kind of this white area

that we see around the head,

which would most likely be a reflective collar.

And it's just kind of running through someone's garden.

[Slow dramatic music]

- So our verdict.

This is just a dog on the loose, not a runaway raptor.

But again, thanks to Florida's laid back

exotic pet regulations, gigantic lizards

have gotten free in the sunshine state.

So there's a chance Christina might capture some footage

of a living dinosaur descendant any day now.

That's our show for tonight.

Thank you so much for watching.

And remember to keep those cameras rolling.
