Ancient Aliens

This was the language of the Gods.

Did extraterrestrial beings

leave behind coded messages?

We may find information that is vital to mankind.

Messages that are carved in stone

and found all over the world?

There has been an explosion

in new discoveries of geoglyphs

that we didn't know about before.

But once deciphered,

will they reveal a message of hope...

Many of the geoglyphs were created

in order to contact someone up there.

...or a deadly warning?

Just imagine if we don't get that message.

Humanity could be in the balance.

Saudi Arabia. 2004.

While exploring the ancient lava fields of Harrat Khaybar,

amateur archaeologist Dr. Abdullah Al-Saeed

comes upon a number of what appear to be stone walls,

each approximately three feet high.

From the ground level, Dr. Al-Saeed concludes

that the structures have no discernable pattern or purpose.

That is, not until four years later,

when he obtains satellite photos of the very same area.

What he sees astounds him.

There, detectable from the sky are a vast collection

of more than 400 stone enclosures.

Known to the local Bedouin as the Works of the Old Men,

these mysterious structures are quickly examined

and are revealed to stretch for hundreds of miles.

They were within what's referred to

as-as a lava field of activity.

They're generally described either as kites

or as gates,

which are more rectilinear forms of them.

And there are literally hundreds of these.

In fact, they stretch all the way from Saudi Arabia

right away across to Jordan and into Syria.

They're kind of like angular pyramids

almost going off into the distance like runways,

widening at one end to being short at the other end.

Although no record exists

indicating when these structures were built,

who built them or why,

the predominant theory among mainstream archaeologists

is that they were constructed for hunting purposes

many thousands of years ago.

What we think they are are prehistoric hunting sites

where gazelle and other animals

would be driven into the enclosure,

and then on the outsides of the enclosure, pits were dug

and the animals would fall into the pits.

The kites, when you visit them on the ground,

are really hard to find.

In the air you get the whole pattern.

There are literally thousands of them.

And they must have been in use for thousands of years.

And why did they fall into disuse?

That's an answer we haven't yet got.

Although the theory that the stone structures

were used for hunting purposes is compelling,

ancient astronaut theorists argue that if these structures

were really used for hunting gazelle,

the walls would have needed to be more than three feet high

since a gazelle can leap more than ten feet into the air.

Instead, they suggest that because the structures

are only viewable from the air,

they should be considered geoglyphs.

A geoglyph is just basically

a drawing on the landscape, usually quite large scale.

Most geoglyphs are in deserts,

and in deserts you get a phenomenon

which we call desert varnish.

It's just a natural dark patina that builds up on the surface.

So if you move the dark parts to one side,

expose the lighter soil or sand underneath,

that is one way of making a drawing.

The second basic technique is to use the dark stones

and pile them together to make shapes.

Geometric shapes, animal shapes or whatever.

And the third basic technique is simply a combination of the two.

You move things to one side to expose lightness,

you use the dark stones to make patterns.

So, you get very nice combination of the two.

In recent years, thanks to modern technology,

and particularly satellite photographs,

uh, there has been an explosion in new discoveries

of-of geoglyphs that we didn't know about before.

The interesting fact about all of these

is that they point towards the sky.

And what might this tell us?

Well, the first thing is that many of the geoglyphs

that we know today were only discovered

once aerial survey started in around the 1920s.

All of them were only really revealed

once aircraft got up into the air.

And this tells us something very, very important.

Most geoglyphs really only make sense from above.

It therefore seems that they would be messages

to something nonhuman, something up there.

When the now legendary Nazca Lines of Peru

were first discovered in 1927,

they were considered a unique phenomenon.

But now, with the benefit of satellite imagery,

thousands of ancient geoglyphs

are being found all over the world:

in Kazakhstan, in the Southwestern United States,

in the Atacama Desert of Chile and in Bolivia.

Almost everywhere around the world,

we find what are known as geoglyphs.

Whether they be the Nazca Lines in Peru,

British geoglyphs to those in the Middle East,

they're something that are virtually universal

around the world and they've been appearing

for many hundreds of years.

But why would ancient people

in so many different locations around the world

all be making signs that can only be seen from above?

We don't know for sure what ancient peoples

were trying to communicate through geoglyphs,

but the most important thing is the amount of time and effort

that went into building them.

They're not quick sketches.

They're, many of them, whole community projects.

And the time that you spend working on them

is time not spent gathering food,

not spent defending your land.

It's time not spent looking after your children.

So, the first thing that they communicate

is to the community itself what is important to the community.

But could there be another

even more incredible explanation?

Is it possible that these ancient geoglyphs were created

not for a terrestrial purpose, but for an extraterrestrial one?

Ancient astronaut theorists say yes,

and suggest further clues can be found

by examining similar shapes and symbols

that occur on a much smaller scale.

Geoglyphs are gigantic-sized versions

of what we know as petroglyphs,

the most obvious being the rock art that we'd see

on surfaces of stone rock around the world

that date back many, many thousands of years.

Petroglyphs are images carved into stones or incised

or hammered away.

They occur all over the world from Australia up through Asia,

Europe, Africa, through the Americas.

Perhaps more intriguing

than the petroglyphs themselves

are the eerie similarities between them

and their geoglyphic siblings.

We see certain symbols recurring again and again.

There are many geometric forms.

These take the form of, uh, spirals,

of concentric rings

and other more rectilinear or abstract designs.

They're something that are virtually universal

around the world.

One of the most interesting geoglyphs that you have at Nazca

is the sun, star, cross geoglyph,

which is really a very complicated huge mandala

of interconnected stars and triangles.

And it's something we see all over the world

and in Tibet and India as mandalas and even yantras.

So, things like this that are so geometrically complicated

and are found all over the world

indicates that there was some kind of worldwide

symbolic language that was brought here

by a higher intelligence, probably extraterrestrials.

Is it possible that the thousands

of mysterious petroglyphs and geoglyphs

found throughout the world

were intended to be a form of communication

between early humans and extraterrestrial visitors?

Ancient astronaut theorists believe that proof

of such a profound idea does exist

and it can be found by examining an ancient story

associated with one of the oldest petroglyphs

ever discovered.

Northwest Nevada. 2013.

In the dried-up bed of what was once Winnemucca Lake,

researchers take carbonate samples

from a series of recently discovered limestone boulders.

They are covered with what appears to be ancient carvings.

Some of the petroglyphs are believed to be depictions

of ancient shipping techniques,

but others are much more difficult to identify.

Even more mysterious is the fact that the local Paiute people

say the petroglyphs were not created by their ancestors,

but by a race of giants.

The Paiutes said that

initially they did not create petroglyphs,

that an ancient race called the Si-Te-Cah did.

The Si-Te-Cah was a race of giants

that was said to have been white-complected,

having red hair, and well over seven-foot tall.

The Paiutes explained that these giants lived on the lake...

In Pyramid Lake, on floating cities.

And each Paiute legend has their own versions
