PATRICIA CROWN: This is room 28, a small room, but one that has been critical in our understanding of Chaco.

NARRATOR: First excavated in 1896, Room 28 contained dozens of cylindrical pots.

CROWN: They really seemed to be drinking vessels, I just wasn't sure what they might have been drinking in them.

NARRATOR: Patti took a closer look using forensic technology, and what she found was a complete surprise... Chocolate.

Chocolate comes from the cacao bean, and cacao only grows on trees in the tropics of Central America, more than 500 miles away.

Here, chocolate was considered food for the gods, used in ceremonies where it was poured between vessels, shaped like those found in Chaco.

CROWN: The cylinder jars are actually created in sets, and so one might be placed on the ground and the other used to pour from a height, creating this cascading waterfall of chocolate with bubbles at the bottom.

(chocolate splashing) NARRATOR: Chocolate and its sacred drinking ritual must have travelled from Central America to Chaco.

And chocolate is just one of many sacred objects discovered here.

Carved shells from the Pacific Ocean and Gulf of Mexico.

Precious metals and minerals, like turquoise from far-off mountains.

Archaeologists Anna Roosevelt and Chris Davis are searching for the earliest evidence of people in the Americas in the Amazon rainforest of western Brazil.

Their destination is a cave on this mountaintop rising out of the jungle.

This is the Caverna da Pedra Pintada, Portuguese for the "Cave of the Painted Rock."

DAVIS: That's amazing.

There's art going from the base all the way up to the ceiling.

NARRATOR: The cave is covered with paintings inspired by animals and the sky.

In this case there's a round object in the middle of the depiction of the turtle.

DAVIS: Yeah, a lot of them are very abstract.

ROOSEVELT: The local people, speculated that these were suns or moons-- And that might match with the turtle, because also turtle myths were related to the sun as well as a creation spirit.

NARRATOR: This cave in the Amazon is rewriting the history of when and how people settled the Americas, and who those people are.

♪ ♪ For decades, textbooks presented only one view-- around 11,000 B.C., during the Ice Age, big game hunters cross a frozen land bridge from Asia into Alaska, a region known as Beringia.

After the ice melts, they migrate down into the virgin territory of North and South America, (animals growling) hunting mammoths, giant sloths, and caribou, with finely fashioned stone spear points.

(birds squawking) The standard view is that people reached the Amazon about a thousand years ago.

But what Anna excavated in the Cave of the Painted Rock changes everything.

ROOSEVELT: The remains we found and dated in the cave show that people were living deep in the Amazon forest at 13,000 years ago.

This is some of the earliest art in the world and it's definitely, so far, the earliest art in the hemisphere.

(birds chirping) Chris is a specialist in archaeoastronomy, the study of how ancient peoples looked at the sky.

(birds chirping) DAVIS: Something is going on here that they were observing, and probably tracking, and tallying with this grid.

Because this is an open-air site, maybe they were counting something in the sky, and this big grid represents something of a calendar.

NARRATOR: To Chris and Anna, these images are calculated observations of the sky and nature.

DAVIS: What this art represents is very sophisticated thinking.

ROOSEVELT: This art links people with their environment through its animals, its plants, and the heavenly bodies of the sky.

NARRATOR: These paintings are the earliest art ever found in the Americas.

They suggest that people 13,000 years ago had already developed ideas and beliefs about the world that centered on the sky, caves, and nature.

But what exactly are these First American artists trying to say?

Part of the answer may lie a continent away in an ancient ceremony performed by the Hopi back at Chaco.

(indistinct chatter) KUWANWISIWMA: The reason we do these pilgrimages is to continue our connection to places like Yupköyvi, which is the Hopi name for Chaco.

♪ ♪ NARRATOR: Built in northwest New Mexico between 900 and 1150, Chaco grows to cover an area roughly the size of modern San Francisco.

They were once covered, but their roofs have collapsed with time.

They are called kivas.

Back home in Arizona, the Hopi still use them today.

The kivas are very special settings where both men and women conduct different ceremonies.

So, a kiva that is a thousand years old is a very special setting for us.

NARRATOR: Prayers and rituals inside center on rainmaking, healing, and hunting, all to ensure the continuation of life.

But Pueblo people have an even deeper connection.

This is their birthplace.

ENOTE: When we come to a place of water, we take the water, we put it on our head, and we splash that water, we lift it and throw it into the air in the direction of Zuni, to encourage rain, four times, and then we drink the water.

NARRATOR: Jim Enote is an elder of the Ashiwi, a Pueblo group in what is now New Mexico, known as the Zuni.

Jim is mapping ancient images of the Zuni's origins, carved in stone by his ancestors.

FRANCESCA BOB: Just one hefty push.

Not limited by lines or topography, they depict cultural landscapes and living memories.

ENOTE: The Zuni maps represent the world without defined boundaries.

Many people are familiar with geometric maps with streets and roads.

And then when they see Zuni hand-painted maps, they realize there is a different way of looking at the world.

NARRATOR: This different way of looking at the world is shared across Native America.

It is a reverence for place-- Sacred caves, underground sanctuaries, grand canyons, real physical connections to earth.

It's why many call it Mother Earth.

And as the clans migrated, they placed an insignia of where they were at that particular time and place, which is a spiral.

It's about the people moving from one place to another, living in some place, testing it, moving on and on until they finally find the right place.

This search for the center place is built right into the kivas.

Every kiva is aligned to the four compass directions: north, south, east, and west.

That's true north, and this one is true south.

So the sun rises here in the east, and then sets to the west there.

NARRATOR: There are two more sacred directions: up and down.

(fire crackling) Climbing a ladder out of a kiva is symbolic of emerging into this world.

The Hopi believe the six directions give kivas great power.

♪ ♪ The sacred power of six directions is shared by many peoples across Native America.

One of its purest expressions was recently discovered in a man-made cave near Mexico City.

Here, almost 2,000 years ago, is the largest city in the Americas, Teotihuacan, population 125,000.

The name of its builders is lost to history, but it would take more than 1,500 years for a U.S. city, New York, to surpass its population.

Its biggest pyramid is one of the largest in the world, after Egypt's Great Pyramids of Giza.

Yet archaeologist Sergio Gomez is more interested in what lies underground, a previously unknown man-made cave.

(Sergio speaking Spanish) SERGIO GOMEZ (translated): In almost every Mesoamerican culture, caves have a deep significance in cosmological thought.

That is why this discovery is so important.

NARRATOR: In 2003, a monsoon rainstorm created a sinkhole near a pyramid known as the Temple of the Feathered Serpent.

(Sergio speaking Spanish) (translated): The entrance to the tunnel is located under the white tent, at a depth of 14 meters.

NARRATOR: Sergio was the first to rappel down the sinkhole.

(machine whirring) It led to a tunnel, carved 2,000 years ago.

Inside, he found artifacts brought here from vast distances, just like at Chaco.

(speaking Spanish) (speaking Spanish) (translated): This is one of the thousands of pieces, of artifacts that we have discovered in the interior of the tunnel.

It's a representation of the principal deity of both the underworld and the celestial region.

NARRATOR: Sergio believes many of the offerings symbolize heaven and earth, and are carefully positioned in the tunnel.

(speaking Spanish) (translated): We believe that the placement of each object throughout the tunnel had a particular meaning.

They were not just placed there randomly.

NARRATOR: The tunnel ends in a human-made cave.

Its floor is sculpted to represent the underworld.

Its ceiling is covered in artificial starlight, mimicking the cosmos.

♪ ♪ (Sergio speaking Spanish) GOMEZ (translated): The entire tunnel was originally covered in a dust of shiny metallic mineral.

They covered the walls and ceiling of the tunnel so it's as if you were seeing the sky and the stars twinkling.

NARRATOR: In this cosmic sanctuary of stars, Sergio finds two stone figures, statues that depict the first man and woman in the city's origin story.

Sergio laser scans the tunnel.

It descends 50 feet underground, extends for 340 feet, and ends directly beneath the Pyramid of the Feathered Serpent.

Here, the Teotihuacanos place the founding couple, within 16 inches of the exact center of the pyramid.

(Sergio speaking Spanish) (translated): We are positioned exactly under the intersection of the north-south axis and east-west axis.

And above us is the peak, the central point of the Temple of the Feathered Serpent.

Right in this spot.

They believed there was a conduit that connected this region from the underworld to the celestial region.

♪ ♪ NARRATOR: The builders went to extreme lengths using precise math and masterful engineering to align their sanctuary of stars to the six directions.

Just like the kiva builders at Chaco, the early Mesoamericans share a belief that the six directions represent finding balance in the universe.

It is a quest to find the center between the world below and the one above, between caves and the cosmos.

(Sergio speaking Spanish) GOMEZ (translated): In the southwestern United States, including Central America and South America, there are a series of ideas that form a general concept of the cosmos.

I've heard and read of the ideas the Hopi have about the cosmos and how the universe was created.

These ideas are shared throughout many indigenous communities, including indigenous communities in Mexico today.

NARRATOR: Teotihuacan is part of something bigger going on across the Americas.

The Maya, Aztec, and Inca, all build monumental cities aligned to compass directions and with an eye to the worlds above and below.

♪ ♪ And at Chaco, the builders extend the science of six directions to apply not only to place, but also to time.

WADSWORTH: Alignment was very important to these people at Chaco.

It helped them to determine the times of year, the cycles of their crops, when they plant certain seeds.

And it also determines the months, the moons when the certain ceremonies happen.

♪ ♪ NARRATOR: At the very center of Chaco, builders create a sacred space to unify time and place-- Pueblo Bonito.

And we can also talk about it as a clock.

NARRATOR: Park Ranger GB Cornucopia came to Chaco to study the stars 30 years ago and never left.

♪ ♪ To GB, Pueblo Bonito and the sky are intricately linked.

The great house is aligned to the six directions.

One wall runs east-west.

And another north-south.

Here we can see the shadow is almost gone.

And in just a few moments it will disappear.

♪ ♪ There...

It's also a calendar that tracks it during the year.

Every day, the sun sets in a different place on the horizon.

The solar year starts on the winter solstice, when it sets in the south.

On the summer solstice, it sets in the north.

The two days halfway in between them are called equinoxes.

And today, on the fall equinox, the sun lines up with the east-west wall.

CORNUCOPIA: We're between the two extremes when it's really hot in the summer, summer solstice, and when it's really cold in the winter, winter solstice.

We're at that midway point.

NARRATOR: The people of Chaco look to the sky to guide their agriculture and their ceremonies.

♪ ♪ Can these ideas really have been developed so far back in time?

If so, they may be expressed in the earliest art found here.

It dates back 13,000 years to the very beginnings of Native America.

Anna Roosevelt and Chris Davis re-examine the rock paintings in Brazil's Amazon rainforest.

ROOSEVELT: It's been assumed that hunting and gathering people were primitive and wouldn't be into art very much.

But everywhere you go in this rocky area, you find a painting.

NARRATOR: Chris believes the paintings may relate to the sky.

DAVIS: All of the rock art is facing the west.

So maybe there was something important in the west, maybe sunsets.

NARRATOR: The cliff wall extends a half mile.

It is covered in paintings of animals, grids, and circles all the way to its far south end.

DAVIS: This is the southernmost image of the painting sequence.

And there's two concentric circles-- one above, and another one below.

NARRATOR: Chris thinks these circles could depict stages of the sun setting.

And their location here to the far south even suggests a specific day: the day when the sun is at its farthest southern point, winter solstice-- the shortest day of the year.

DAVIS: And as it angles downward, it starts to rest on a pedestal.

NARRATOR: Chris suspects that pedestal represents a rocky outcrop on the horizon.

He has come here on the winter solstice to see if the sun will line up with the platform.

If there's a match, we should see it today.

In between, there are images of animals, perhaps constellations, and other important resources.

They are recognizing connections, associations, that when the sun is at this particular point in the sky, these animals are most active, or these changes occur in the environment.

NARRATOR: 8,000 years before England's celebrated Stonehenge, Native Americans paint a cliff face to transform a mountain into a three-dimensional solar calendar.

It is the earliest evidence of tracking astronomical events in the Americas.

DAVIS: They created a calendar that you can walk through, a pictographic almanac that encapsulates this landscape.

NARRATOR: The calendar expresses an intimate knowledge of their new world.

Caves and mountains provide shelter, plants and animals teach them lessons of survival, and the sky helps them find their place in the world.
