In Search of Aliens

The ancient ruins of Puma Punku have mystified archaeologists ever since their discovery hundreds of years ago. The massive stones are precisely carved into blocks that are unlike anything found anywhere else in the world. Is it possible that the ruins of Puma Punku offer evidence of advanced technology being used in the ancient past? And if so, might this technology have been provided by alien beings--beings who ultimately destroyed the site to conceal whatever they built? Ancient Astronaut theorist Giorgio A. Tsoukalos explores the construction and mysterious history of one of the most unique ancient sites on Earth. What was the purpose of the vast building at Puma Punku? Why is there no evidence of the precision tools required to create the unique blocks and sophisticated masonry found there? What could have destroyed this massive structure? Is it possible that Puma Punku is thousands of years older than previously thought?

The imposing city of Washington D.C. was inspired by the ancient world, as seen in the Greek pillars, Roman domes and even an Egyptian-style obelisk that mark the landscape. But is it possible that the designs and philosophies enshrined in the streets of the U.S. capital were influenced by an otherworldly source? Ancient Astronaut theorist Giorgio A. Tsoukalos travels to Washington D.C. and Philadelphia to investigate the origins of the American democratic experiment. Did George Washington have an alien encounter at Valley Forge--one that gave him mystical protection throughout the American Revolutionary War? Does the way Washington D.C. was planned and constructed hold any clues to the beliefs of the nation's founding leaders? Did the Native American stories of Sky Gods play a role in the establishment of the United States? Might the inspirational ideas of reason and science embraced by the Founding Fathers have in fact been seeded by an extraterrestrial intervention?

Nazca remains one of the most mysterious sites on Earth. The vast desert floor is covered with hundreds of ancient geoglyphs depicting animals, human-like figures and strange geometric designs. But, many of these glyphs are so large they can only be fully viewed from the sky. Perhaps even more intriguing are the strange flat-topped mountains that appear to have had their peaks sliced off, and a band of man-sized holes that stretch for almost two miles across the desert. Could these ancient geoglyphs and mysterious landscapes hold the key to proving Earth was visited by aliens in the distant past? Ancient Astronaut theorist Giorgio Tsoukalos, along with author David Childress, investigates the origins and meanings of the mysterious symbols and shapes found in the desert of Peru.

Ancient Astronaut Theory has existed in popular culture for nearly 50 years, asking the question whether extraterrestrials visited Earth in the remote past. All around the world there are examples of physical evidence that suggest humans are not alone in the universe. But has this evidence been left behind for a purpose? Is it in fact a series of clues, or Alien Code, that we are meant to decipher? Ancient Astronaut theorist Giorgio A. Tsoukalos investigates unexplained mysteries from every corner of the world. The evidence shows that many ancient sites, and even modern ones like Roswell, all seem to be associated with legends and reports of someone or something coming down from the sky. Tsoukalos' research demonstrates that many of these sites share a common symbol or shape--concentric circles. What is the significance of these designs, and is it possible they contain a coded, mathematical message left by alien visitors in the remote past?
