WHAT IF LIFE ON EARTH BEGAN IN OUTER SPACE. Is it possible that intelligent life forms visited Earth thousands of years ago, bringing with them technology that drastically affected the course of history and our own development? Originally presented in Erich von Daniken s 1968 bestseller Chariots of the Gods, the theory of ancient aliens rocked our accepted notions of mankind s natural evolution. From the age of dinosaurs to ancient Egypt, from early cave drawings to continued mass sightings in the United States, each episode in this series gives historic depth to the questions, speculations, provocative controversies, first-hand accounts and grounded theories surrounding an age-old debate: did intelligent forms from outer space visit Earth thousands of years ago? Do they visit us now? ANCIENT ALIENS launches all-new expeditions to seek out and evaluate the original evidence, concentrating on discoveries from the past 30 years. It is a balanced investigation into a theory some believe cannot be true, but many agree cannot be ignored. Together for the first time all 15 fascinating episodes of seasons 1 and 2. Produced with the exclusive co-operation of von Daniken himself.
