Return to Gobekli Tepe

In China, hundreds of strange disks are discovered in a cave that appear to tell the story of an ancient extraterrestrial crash on Earth; shortly thereafter, the disks are confiscated by the Chinese government and dismissed as a hoax.

While more than 1.5 billion people believe in reincarnation, ancient astronaut theorists suggest that extraterrestrials designed the human body to be a vessel for otherworldly entities.

Giorgio A. Tsoukalos studies India's Sanskrit texts, which are filled with descriptions of brain surgery, flying crafts, nuclear physics, and other advanced sciences; Hindu scholars attribute this knowledge to a time when gods walked among humans.

Researchers suggest that the ancient site of Teotihuacan in central Mexico was once home to a highly advanced, perhaps extraterrestrial, civilization; excavations at Teotihuacan have unearthed discoveries out of place in the ancient world.

City of the Gods

Archaeologists and anthropologists make discoveries that receive no notice because they don't fit into the accepted scientific paradigm, such as an ancient hammer found in Texas or elongated skulls found on nearly every continent.

The Science Wars

According to legend, a curse was placed on the tomb of King Tutankhamun; researchers theorize that the curse came about as the result of alien technology with the purpose of protecting the truth about an otherworldly event as well as an alien device.

The Pharaoh's Curse
