Did intelligent life forms visit Earth thousands of years ago and bring technologies that affected the course of human history?

How do we make sense of ancient Indian texts describing "flying machines of the gods”? Are there really ancient “landing strips” in Peru? Do aliens visit us now?

ANCIENT ALIENS is a thorough exploration of the theories first proposed by Erich von Daniken in his 1968 book, Chariots of the Gods. Go back to the very beginning of the hit series from HISTORY® as we examine 75 million years of the most credible alien evidence here on Earth, from the age of the dinosaurs, to ancient Egypt, to the skies over the western desert in the present day. Ancient cave drawings of strange creatures, an asphalt-like substance in an Egyptian pyramid made from the remains of unidentified creatures, continued mass sightings around the world – these are just a few of the strange stories that will be investigated.
