GIORGIO A. TSOUKALOS: The megalithic site

known as Puma Punku in Bolivia is unlike

any other place on the planet.

Here, scattered across the landscape

at an altitude of over 12,000 feet,

are giant stone blocks,

each cut with astonishing precision

and some weighing over 100 tons.

Yet no one knows how they got here,

how they were made, or what they were used for.

There are many ancient sites that I am certain

were constructed with the help of advanced beings.

But Puma Punku is so extraordinary

that I think it was built

by the extraterrestrials themselves.

On my most recent visit to Puma Punku,

I was once again blown away

by how incredibly sharp and precise the cuts are

with these giant stone blocks.

In some places it's as smooth as glass.

You can actually cut your finger

by running it along one of the edges.

And this is solid andesite we're talking about,

which is an extremely hard volcanic rock,

not something that is easy to cut.

Clearly the blocks were made to fit together

to form some sort of structure, but what?

And why don't we find stone blocks like this

anywhere else on Earth?

NARRATOR: Bolivia, South America.

Here, 45 miles west of La Paz,

isolated high in the Andes Mountains,

lie the mysterious ancient ruins of Puma Punku.

Spread across a desert plateau

at an altitude over 12,000 feet,

the megalithic stones found here

are among the largest on the planet,

measuring up to 26 feet long

and weighing more than 100 tons each.

These are the mysterious ruins of Puma Punku,

nearly 13,000 feet in the altiplano

of Bolivia.

What you have here are massive blocks of granite

scattered like some kids' toy blocks

around the site.

It's like some giant cataclysm

just wiped out this entire area.

Archaeologists are baffled

by what Puma Punku was,

how it looked,

and what the purpose of this enormous structure

would have been.

NARRATOR: Mainstream scientists

believe the site was originally constructed

about 2,000 years ago.

But in 1945,

archaeologist Arthur Posnansky proposed

that Puma Punku was much, much older.

By examining the structures

and what he believed were their original alignment

with the stars, he dated the ruins

to 15,000 BC.

HUGH NEWMAN: Arthur Posnansky was a researcher

who was part Bolivian, and he worked at the site

for many decades. And he concluded

that the site must've been built about

17,000 years ago by studying the archaeoastronomy

of that particular site.

PHILIP COPPENS: We don't know how old Puma Punku is.

We have had some circumstantial dating,

but we have been unable

to date the stones of Puma Punku themselves.

They could be thousands

if not hundreds of thousands of years old.

We don't know.

GEORGE NOORY: I think the fascinating thing

about Puma Punku is how did these structures get built.

We're talking about stone that is 25 feet high,

stone that is hundreds of tons.

BRIEN FOERSTER: Puma Punku is so unique in the way

that it was constructed and shaped and positioned

that it is the most intriguing ancient site on the planet.

Of all the places I've ever visited,

Puma Punku is the one that I go back to time

and again because no one can solve the mystery.

NARRATOR: Mainstream scholars believe

the andesite blocks found at Puma Punku

were formed by hand with primitive stone tools.

But some researchers point to the intricate stonework

as evidence of the use of advanced precision technology.

One of the amazing things here at Puma Punku

is the precision of the blocks.

You can see with this block of granite

that it's really been cut

at very accurate right angles.

Not only do these granite blocks have precision corners

but they also have these difficult drill holes

that are going right through the rock.

NARRATOR: But how could such primitive people,

living perhaps tens of thousands of years ago,

have produced such flawless stonework?

Might the ancient builders of Puma Punku

have fabricated the megalithic stones with advanced technology,

technology of an otherworldly origin,

as ancient astronaut theorists believe?

CHILDRESS: You know, Brien, this is one

of the most interesting and unusual stones

here at Puma Punku.

It's got these perfect right angles,

and then each of these small drill holes

are basically evenly spaced

along this routered groove.

To me, it's clear that power tools have been used

on this unusual block of stone here.

Well, exactly. And this surface is as smooth

as a tabletop, like in your kitchen.

There's no wave to it or anything.

This was machined.

But who machined it?

It's an astonishing piece of work.

And how anyone could think that primitive human beings

could have done this, you know, it's just crazy.

If anything looks like ancient aliens, it's this stone.

NARRATOR: But if otherworldly technology

was used at Puma Punku,

where is the proof?

In Danville, Illinois,

machinist and toolmaker Chris Dunn

has put the Puma Punku stone

through the ultimate cutting test,

using both laser technology

and a modern diamond saw.

We've got a sample of the laser cut.

This is the diamond wheel cut.

And the top surface is the original cut surface

from Puma Punku.

So now we can compare the difference

between all three cuts.

NARRATOR: Looking at the stone under a microscope,

Dunn compares the two modern cutting techniques

with the part of the stone cut thousands of years ago.

Though age has worn the surface of the ancient example,

the comparison reveals distinct differences.

You've got vitrification on the laser-cut side,

and then, of course, you've got circular tool marks

on, uh, the-the side cut with the diamond saw.

And then whatever tool they used

to cut the ancient surface must have been a different method.

Now, do you think it's possible

that some type of a diamond precision tool

was used on the old surface, but because

it was such a long time ago,

that over time,

the surface became a bit more rough,

and we're talking 10,000, or even 15,000 years ago?

DUNN: That is a reasonable speculation.

I think we have to start examining, um,

a little more sophisticated tools

that no longer exist.

NARRATOR: But how could the ancients have managed to move

the incredibly heavy andesite stones to the site?

After years of research, mainstream archaeologists

have said the massive stones were hewn at quarries

over 60 miles away

and then rolled to Puma Punku on logs.

What nobody talks about is the irrefutable fact

that we are at an altitude of 12,800 feet.

Which means we are above

the natural tree line.

No trees ever grew

in that area,

meaning no trees were cut down

in order to use wooden rollers.

-The wooden roller theory... -[snaps fingers]

falls by the wayside.

NARRATOR: Could there have been another more profound method

of moving these megalithic stones into place?

And if so, how could such an advanced engineering feat

have been accomplished without the help

of modern machinery?

CHILDRESS: How these massive blocks of granite

were moved from their quarries

and brought here to Puma Punku would have required

some kind of super technology.

Levitation and antigravity,

huge lifting vehicles--

something that ancient aliens

would have had.

NARRATOR: Might the ancient city of Puma Punku

really have been built by alien beings,

as ancient astronaut theorists contend?

Some researchers believe the ultimate proof

can be found nearby

and also carved in stone.

TSOUKALOS: On my most recent visit to Puma Punku,

I met with local historian Rene Quispe.

I was fascinated to learn

that he is one of a growing number

of researchers who believe that the site is much older

than what mainstream archeology has suggested.

How does he react when

people say, for example, that

this place here could have been

built more than 10,000 years ago?

[speaks foreign language]

TSOUKALOS: He told me that many people outside of Bolivia

won't accept this dating because they refuse to believe

that the local legends could actually be based

on real history.

According to the ancient stories, Puma Punku was built

by so-called sky beings

and that the recorded proof of their time on Earth

can be found in Tiahuanaco,

where the Inca say mankind was created.

NARRATOR: Southern Peru. 1549.

While searching for the capital of the Inca Empire,

Spanish conquistadors,

led by Pedro Cieza de Le�n, cross into Bolivia

and discover the ruins of Tiahuanaco.

Less than a quarter mile northeast of Puma Punku,

mainstream scientists believe Tiahuanaco was once the center

of a civilization

with more than 40,000 inhabitants.

PAUL GOLDSTEIN: Tiahuanaco is probably the greatest

Native American civilization

that many people haven't heard of.

It was one of the most important antecedents of the Inca.

It was long gone by the time the Spaniards came on the scene.

Yet its level of achievement in architecture,

in political development,

in agriculture, in many craft industries

are on a very high level.

NARRATOR: Most scholars agree that Tiahuanaco

was mysteriously abandoned around 1100 AD.

But why?

Local legends suggest that Tiahuanaco was built

as a site of religious pilgrimage to celebrate

the arrival of sky gods at nearby Puma Punku.

According to ancient astronaut theorists,

the two sites were not only

built at different times,

but also by beings from different worlds.

COPPENS: Puma Punku, I think, is very of the gods.

And I think mankind did very little with that site.

And then nearby our ancestors built Tiahuanaco

as a place where people could come to explore

these places, but also, I think, as a tribute site

where a god had once been

physically present on planet Earth.

ERICH VON DANIKEN: You have to differentiate

two different styles of construction:

the old style, which I call the extraterrestrial style,

and then the later style,

which was made by the humans.

Tiahuanaco is nothing else

but a place of pilgrimage

for people to congregate

and remember the time

when something significant happened at Puma Punku.

And the thing that was significant about it

was an extraterrestrial visit

by ancient aliens in the remote past.

NARRATOR: But if Tiahuanaco

was built to honor extraterrestrial contact,

as ancient astronaut theorists contend,

might there be tangible evidence?

In the 1960s the Bolivian government

excavated and unearthed the subterranean temple

at Tiahuanaco.

Within the walls of the square, sunken courtyard

are hundreds of stone heads

with a diverse range of features.

CHILDRESS: Here at the famous sunken temple at Tiahuanaco,

we have all of the different heads

that have been inserted

into the walls.

It's sometimes said that

there are all the races

of mankind represented here,

even elongated skulls, people

wearing turbans, people

with broad noses,

people with thin noses,

people with thick lips,

people with thin lips,

and some of the statues

are particularly unusual.

FOERSTER: They don't seem to represent the local people.

They seem to represent every type and shape

of human head existing on the planet.

Two of them, which are very intriguing,

are white in color, and they look

very much like Grey alien heads.

COPPENS: When we're looking at the carved heads

of the Tiahuanaco complex, you really see

that it's almost as if this is a U.N. headquarters,

whereby everybody was able to come there because all cultures

on planet Earth accepted

that Tiahuanaco was so special

because this was a place

where contact with the divine had been made.

NARRATOR: Some researchers believe a large statue

at the center of the sunken temple

depicts the creator god

known as Viracocha.

But why would the inhabitants of Tiahuanaco

have depicted their most prominent god

with features unlike their own?

CHILDRESS: He has got a beard

and a mustache.

And that is an unusual thing,

because American Indians

do not have beards and mustaches.

FOERSTER: Exactly. The fact, also,

that the beard and the mustache

are so pronounced. They're not little wispy ones,

they're major, so that indicates that this person

was not a South American Native,

but clearly came from another land.

CHILDRESS: And an important person, too,

who's somehow, uh,

one of the founders here of Tiahuanaco.

Maybe even somebody who's come from Sumeria

to South America.

NARRATOR: Is it possible that the Sumerians--

a civilization established in 4000 BC

and located nearly 8,000 miles away--

could be connected to the early inhabitants of Tiahuanaco?

If so, how?

Ancient astronaut theorists believe the answer can be found

at the Precious Metals Museum

in La Paz, Bolivia.

CHILDRESS: This is perhaps

one of the most important archaeological artifacts

ever discovered in Tiahuanaco or Puma Punku.

This is the famous Fuente Magna bowl

discovered near Tiahuanaco.

It's a ceramic bowl,

and it has written on it Sumerian cuneiform

plus proto-Sumerian hieroglyphic script.

This script is coming from circa 3000 BC.

It draws a direct connection

between the ancient Sumerians

and Tiahuanaco and Puma Punku.

NARRATOR: Discovered near Lake Titicaca

by a local farmer in the 1950s,

researchers believe the vessel provides proof

of extraterrestrial intervention at Puma Punku.

CHILDRESS: The idea

of Sumerian writing being here

at Puma Punku and Tiahuanaco...

...would seem to relate to the late Zecharia Sitchin,

and his ideas that the Sumerians

were also interacting

with these space beings

called the Anunnaki.

So in that case, the Anunnaki were there in Sumeria,

but also here at Puma Punku

and Tiahuanaco in South America.

NARRATOR: Could the stone sculptures

found at Tiahuanaco really be evidence

of interaction with extraterrestrial beings,

as ancient astronaut theorists believe?

Perhaps the answer can be found

by examining the legends of the creator god Viracocha...

and his mysterious origins.

NARRATOR: The Andes Mountains, Peru.

Here, 12 miles north of Puma Punku,

lie the murky waters of Lake Titicaca,

the largest lake in South America.

According to local legends,

the god Viracocha rose up from the depths of this lake

to create the sun...

the stars...

and mankind.

NEWMAN: Legend states that Viracocha,

the great creator god of the Inca

and the prehistoric civilization of the area,

emerged from Lake Titicaca.

And he went to Tiahuanaco

and brought civilization to that part of the world.

He then went to Puma Punku,

and this is where he said he made men and women from stone

and took them to the four corners of the Earth

to spread their seed.

VON DANIKEN: The Spanish conqueror

asked the Inca, the people living there,

including the king of the Inca,

what is this Puma Punku?

And they all said: It's not us.

It's not our forefather who make this.

These were made by the gods in one single night.

Usually, a king is proud

about what his people did,

about the precision and so on.

In that case, the chief and the people said:

No, it was not us.

It was the gods who made it.

NEWMAN: One of the legends of Puma Punku states

that it was built by a race of giants in one night

after a great cataclysm and flood

had destroyed the whole area.

But what's really interesting is that, who were these giants?

Where did they come from?

Was it Viracocha and his band of followers?

Was it some other beings from some other place?

One of the earliest chronicles that we have

in regards to Puma Punku talks about

that these giant platforms were moved through the air

-[horn blowing] -by the sound of a trumpet.

They basically floated into place.

So do we have some type of sound technology here?

And the answer is a potential yes.

NARRATOR: Might the legends of giants

and stones floating through the air

have been inspired

by some sort of mysterious events in the distant past?

Or were they the result of alien beings visiting Earth

in prehistoric times,

as ancient astronaut theorists believe?

VON DANIKEN: Now, I come with the speculation.

Extraterrestrials arrive.

The spaceship stands in orbit.

Only a smaller space vehicle comes down,

like a space shuttle.

So just to protect

their instruments, they make, overnight,

with their technology what we call a base camp.

Of course, made out of stones found on Earth,

because you don't transport granite or diorite

from another solar system.

And then they disappear.

But the wall of their base camp is still there.

Now the natives come.

They see these ruins.

They touch it with their fingers.

They say: Look at this, it's so smooth,

it's so sharp-- the gods did it.

The place becomes a holy place.

And now the natives start to construct temples,

altars in honor of the gods.

So you have two technologies.

One was an extraterrestrial technology,

and the other was the humans

with their altars and their temples.

The suggestion that some sort of levitation technology

was used to move the giant H-blocks at Puma Punku

has always intrigued me, because we find similar stories

about this all around the world.

According to local legends on the island of Pohnpei,

strange visitors created the ancient city of Nan Madol

by floating giant stone columns into place.

The story behind Stonehenge in England

is that the wizard Merlin

transported those massive stones through levitation.

And even in the 20th century,

we have the story of Ed Leedskalnin,

a Latvian immigrant in Florida,

who claimed he built the incredible Coral Castle

using the secrets of the pyramids-- ancient techniques

for transforming stones into weightless objects.

I propose that the same technology

was used at Puma Punku, and I think further proof

can be found carved into a stone arch at Tiahuanaco

called the Gateway of the Sun.

NARRATOR: In the center of the temples at Tiahuanaco

lie the ruins of a stone arch called the Gateway of the Sun.

Cut and shaped from a single andesite stone

weighing more than ten tons,

archaeologists believe the ten-foot-tall,

13-foot-wide megalith

was once the gateway...

leading to Puma Punku.

GOLDSTEIN: The Gateway of the Sun

is probably the entrance,

or one of the entrances, to the Puma Punku temple,

and as such, it's very important,

because this is how the people of Tiahuanaco

conducted their ritual,

by funneling people through increasingly smaller gateways

and stairways to more and more sacred precincts.

NARRATOR: On the upper portion of the arch,

intricate carvings can be found of nearly 50 winged beings

on either side of what is believed to be

the great creator god Viracocha.

Interpretations of the engravings

suggest they refer to a calendar

describing a time as far back as 27,000 BC.

So here we are at the famous Gate of the Sun with the...

Viracocha right in the middle, holding two scepters,

surrounded by bird men.

That's a common depiction in ancient societies,

is a man who's able to fly, that would have probably been

an interpretation by the Native people

of someone coming from the sky or from the heavens.

?

CHILDRESS: It's part of our idea, too, that...

some giant airship that was a factory,

with power tools and power saws

and routers and drills,

just landed here and began...

processing these giant blocks of stone,

and then ultimately created Puma Punku.

?

NEWMAN: It seems like the whole complex

was some kind of technological kind of factory.

And if my research is correct,

it looks like they were using it

to create energy of some sort.

So what some people

suggest is, is that they were using electricity

and power tools, which sounds incredible

when we think about it, because they're a modern invention.

But actually, if you look at the quality

of the stonework, you have to admit

something like that was going on there.

CHILDRESS: When you look at the complexity of Puma Punku,

the huge platforms,

the interlocking blocks that was made

into what they thought were indestructible walls...

...what you could have

is the kind of perfectly made

granite spaceport that extraterrestrials would want.

In March of 2015, archeologists from the Tiahuanaco

Archeological Research Center made an incredible discovery--

an underground pyramid less than a mile from Puma Punku.

Using ground-penetrating radar,

they also detected other underground anomalies

which they suspect could be monoliths.

Excavations have just begun,

but I think that these new discoveries

might offer further proof

that Puma Punku was built by extraterrestrials.

But what was it built to be?

What did it look like before it was destroyed?

That is what I traveled all the way to Illinois to find out.

NARRATOR: January 2011.

Researchers survey and measure

the monolithic stones and H-blocks

scattered around the archeological site

of Puma Punku, hoping to solve the mystery

of what these structures were used for, and why.

TSOUKALOS: The evidence that something extraordinary

happened at Puma Punku

is in front of our very eyes.

Because at Puma Punku,

we find evidence of stone cuts

that we today could only replicate if we use

the most sophisticated of technologies.

NARRATOR: In Danville, Illinois, toolmaker Chris Dunn

uses measurements taken at Puma Punku

to create a one-eighth-scale model

of an H-block to better understand

how they may have originally fit together.

So you actually went to Puma Punku to measure the H-blocks.

What was your conclusion? What did you find?

For me, it was important to find out what the measurements were.

What I found was that the internal cavities

were not parallel to each other.

And by "internal cavities," you're referring

-to these two parts right here, right? Mm-hmm. -Exactly.

These two surfaces right here, both top and bottom...

they are smaller at the front than they are at the back.

TSOUKALOS: Essentially suggesting a dovetail.

DUNN: Creating a dovetail.

TSOUKALOS: Mm-hmm. Why do you think a...

dovetail shape was carved or used?

Really, if we look at the way wehave used dovetails,

we use them for mechanical purposes,

to hold things together.

So essentially what I'm saying

is that they were using these H-blocks

for a mechanical purpose.

Probably to hold hinges for a door.

NARRATOR: To test his theory,

Dunn created a door hinge that would connect

to a small-scale model H-Block.

So if we put this together, we put the one in the bottom,

like so...

one in the top part...

like so,

and then...

this piece fits in there,

put a hinge pin in it,

and now you have your hinge.

TSOUKALOS: Yeah, it's absolutely spectacular.

And, of course, the most fascinating question is,

what tools were used 5,000 years ago?

Because something very sophisticated was used,

and not chicken bones.

Not chicken bones, not, uh, copper chisels,

not, uh, stone chisels.

The tools that were used to create

these blocks at Puma Punku

do not exist in the archaeological record.

NARRATOR: According to Dunn,

the H-blocks may have been used to mount hinges

for a massive door--

perhaps for one of the largest temple complexes

in the ancient world.

TSOUKALOS: It's a spectacular discovery

that Chris Dunn made.

This lends a whole new meaning

to the H-blocks at Puma Punku,

because, possibly, they held something in place.

The question is, what?

NARRATOR: But Dunn's theory on the purpose of the H-blocks

is only one of several recent hypotheses

concerning the complex engineering

found at Puma Punku.

These had a purpose...

NARRATOR: Model maker Paul Francis,

from Dandridge, Tennessee, offers another theory.

So you've recreated these H-blocks

that we can find at Puma Punku,

and you came up with a very interesting idea,

where you put these blocks together,

creating what looks like to be some type of a track.

So tell me more about what went on in your mind.

FRANCIS: When I saw these laid out on the table, I thought

it basically looks like some of the World War II launch ramps

that the Germans used in testing rocket-propelled airplanes.

?

When I saw this, the lightbulb went off

in my head, and I said, yeah, with some wooden skids

this would make a perfect launching platform

for an ancient spacecraft.

So the skid would travel down the H-blocks,

and eventually, at the end, this would fall off,

and, of course, the airplane would continue to go on.

And this is what I envision an airplane looking like.

And this plane,

it has an intake, it has your control panels,

your control surfaces, and basically,

I mean, this thing is...

ready to go into outer space.

NARRATOR: The concept for the ancient spacecraft

is based on gold jewelry found in tombs

near Bogot�, Colombia.

After careful analysis

and modern testing of reproductions

of the gold object,

ancient astronaut theorists

suggest such artifacts--

nearly 1,500 years old--

are proof of modern aerodynamic capabilities

in the ancient past.

FRANCIS: You know, when these original sculptures

were produced, they're doing a literal interpretation

of what they saw.

I have to take that interpretation

and I have to make it into something

that would actually work as a machine.

So in doing so,

we've added a cockpit,

which the original model does not have.

Also, there are two small bumps

on the back of the original sculpture,

which, to me, indicate rocket thrusters.

You have this... cone-shaped piece,

which could've been an intake that this person saw.

TSOUKALOS: And we know that

these objects truly fly.

We know that, 'cause these experiments

have been done before, and they were experiments

that were repeatable--

meaning they satisfy the scientific method.

And so your idea

of using the H-blocks

as a type

of a launching ramp,

to me, is ingenious.

I've never heard it before

and it's always great

to explore new ideas

in this field.

NARRATOR: Might the H-blocks at Puma Punku

really have been used as launch ramps

for alien spacecraft?

If so, what happened to these massive,

seemingly indestructible structures?

NARRATOR: Puma Punku.

For centuries, researchers have been unable to explain

what may have caused the total destruction

of this ancient site.

Some believe a massive earthquake in prehistoric times

may have scattered its mega-ton stones

like toy blocks.

TSOUKALOS: Puma Punku looks

like some type of a junkyard.

It's as if the whole place at some point

got destroyed and ripped apart

in some type of an upheaval.

Puma Punku seems to have become a victim

of a massive flood of some kind

several thousand years ago.

There is evidence that a meteor

or a comet struck

south of Lake Titicaca,

creating a wall of mud

at least six or ten feet tall

that covered the entire area.

And we can see evidence of that today.

NARRATOR: At recent excavations of Puma Punku,

researchers have discovered that bits of andesite stone

from the structural blocks

are thoroughly mixed in with the soil.

Might such findings of this unusual soil composition

be the result of a large-scale explosion

in the remote past,

as ancient astronaut theorists believe?

CHILDRESS: One possibility is that Puma Punku was destroyed

in some artificial blast

that literally blew these buildings apart.

And then, later,

some cataclysmic tidal wave

also just covered it with mud and muck.

FOERSTER: Some of these stones are so smashed to pieces

you can find them anywhere

in the area. You'll find pieces of diorite

with the angles on it. So that was part of Puma Punku.

So much of it is not simply broken.

It's shattered...

to the point where you can find little tiny pieces of diorite

anywhere you look.

And that looks to me like an explosion happened.

CHILDRESS: When you look at the construction techniques,

it would seem indestructible

and yet it was destroyed.

NARRATOR: But if the structures at Puma Punku

were constructed with such precision,

and with the heaviest,

most durable materials available,

how did it end up in ruins?

Is it possible,

as ancient astronaut theorists believe,

that Puma Punku may have been struck

by a devastating meteor?

Or could there be an even more incredible

explanation for its demise?

There could've been an alien battle out there

where they were using technology--

perhaps nuclear...

...that blew up everything in the region,

that's very possible.

Something could've happened with our Earth's shield

where the sun's rays came through at a certain time

and just burned everything and obliterated it.

The only thing we know for sure is those people

at Puma Punku are gone.

We just don't know how

or where they went.

CHILDRESS: It's hard to imagine the devastating destruction

that occurred here.

It would seem like extraterrestrials

had some cosmic battle on planet Earth before they left.

COPPENS: There are various sites across the planet

where it is said that there was contact

with non-human intelligences.

But when it comes to Puma Punku, what you have is also

the archaeological remains,

which tells you something out of the ordinary

was happening here.

And when you lay upon the layer of mythology,

which says that the gods were here,

I think it is an absolutely convincing case right now

to conclude that Puma Punku stands out

as one of the preeminent sites

where E.T. will have been in residence on this planet.

And so the question, then, is Puma Punku

being a base camp for an E.T. civilization

here on planet Earth-- if they left--

does that potentially mean that when they left

that somehow they destroyed Puma Punku as well?

FOERSTER: If they made this to be a factory or something,

at the end of its use

they may have simply blown it up.

Because they didn't want anyone

to use the technology that they had left behind.

CHILDRESS: The ancient Indian epics--

the Ramayana, the Mahabharata--

they're talking about these horrific wars that happened

in the past with airships,

these vimanas,

spacecraft,

huge, destructive weapons like atomic weapons,

so maybe Puma Punku was destroyed

in this ancient planetary war.

FOERSTER: Since it is unique to the area,

it may have been a... an outstation or something

for another civilization. Possibly from India,

possibly from Atlantis, possibly from...

-Outer space. -Exactly.

TSOUKALOS: With its highly precise stonework

and sophisticated design, I think Puma Punku

is one of the most significant

archaeological sites on the planet.

For me, it provides hard proof

that extraterrestrials came here

tens of thousands of years ago.

But was it an extraterrestrial outpost?

A fortress?

Or perhaps some sort of interplanetary base camp?

Only time and additional research

may tell us.

Perhaps when we unearth the underground pyramid
