NARRATOR: 2011, the Middle East.
Satellite and aerial
photography reveals high numbers
of mysterious stone wheels
carved into the earth in Syria,
Saudi Arabia, and Jordan.
First discovered in 1927,
these stones circles
are believed to number
in the thousands
and date back more than 2,000
years, ranging in size from 80
to more than 200 feet in width.
Ancient astronaut theorists
believe these designs
fit a global pattern.
 It seems to me that
there was high intelligence
behind everything that has
been constructed and built
and that it has all
been built for a reason.
Somebody decided to make these
amazing circles with spokes.
The same thing in Peru, and
look at how far apart we are.
Peru is in one hemisphere,
and Jordan and Syria and Saudi
Arabia are in
another hemisphere,
and they are on two
sides of the planet.
But you're talking about a
similar kind of, shall we say,
communication?
 Thanks to Google Earth, we
now have a vehicle by which we
can see some of these glyphs.
They're being called
Nazca-like phenomena.
I think we are opening the
first page of a chapter that
deals with glyphs and structures
which can be seen from the air.
 It's not only in Nazca
that ancient man was trying
to communicate to the
heavens, but around the world
we are finding new monuments and
glyphs that raise the question,
was there a connected
geodetic presence of sites
that the extraterrestrials used
to navigate around our planet?
NARRATOR: What is the
purpose of the strange shapes
and geoglyphs found at Nazca
and all over the world?
Were they used as
navigational markers intended
to guide space travelers?
Or might they contain a more
profound message for humanity?
In 1972, cosmologist
Carl Sagan stated
that if an extraterrestrial
intelligence
exists in the universe,
the means of contact
would be mathematics.
 If you think about
this as communication,
as Carl Sagan was
quoted as saying,
it is certainly true that
this would be the way
we'd probably have to start.
A circle is a circle, and
that's just a universal feature
of geometry.
And it would be
the same no matter
where you are in the universe.
NARRATOR: Is it possible that
otherworldly beings have been
using basic mathematics
and geometry in an effort
to communicate with us?
And might the proof
of this be found
in the many geoglyphs at Nazca
and throughout the world?
Could mankind have
been receiving
extraterrestrial messages for
hundreds and even thousands
of years, messages that have
gone unread and undeciphered
right before our eyes?
 Imagine you wanted to reveal
a truth about the higher worlds
to humans.
You would lay down
one card at a time.
Each of these cards would be a
glyph or a crop circle image,
and it would reveal something
about the spiritual world.
Not just knowledge,
it would provide
an experience of the actual
reality it was describing.
 What we have in
the Nazca culture
is something which our ancestors
knew that what they were making
was going to have
a lasting effect.
Hundreds of years afterwards,
it is still there.
And it might be very ironic to
realize that they were shouting
out for the deity, saying,
please come down and visit us,
and that 100 years later,
the Nazca Lines have become
the billboard for the ancient
alien theory, whereby they
really are interpreted
as indeed a landing
place for the deities.
And so we might find that across
time and space and culture,
really the core of the
message of the Nazca Lines
is maintained, even
though maybe slightly
placed in a different context.
 When you look at some
of the glyphs at Nazca,
they would seem to be
just simple things--
animals, figures,
and things like that.
But then other of the figures
and the lines seem to be
so incredibly complicated
and mathematical,
and they're-- they're
following energy lines.
So there seems to be a
much deeper meaning in all
of the figures and the lines
and where they're going
and why they intersect,
but we can't figure it out.
NARRATOR: Is it possible, as
ancient astronaut theorists
believe, that the lines
and geoglyphs of Nazca
are part of a worldwide
communications network,
a network that is directly
connected to otherworldly
visitors from the remote past?
And if so, might this form
of alien communication
be intended for us
or for something
or someone not of this world?
Perhaps these strange
shapes and symbols
provide clues to mankind's
not so distant future
or serve as an invitation for
other alien visitors to return.
