The Ancient Astronaut Theory: the idea that extraterrestrials visited Earth in ancient times, influenced ancient cultures in many ways, and departed, i.e. the themes of authors Erich von Daniken, Zecharia Sitchin, Maurice Chatelain, John Michell, R.L.Dione, John Cohane, etc. The theory is based on ancient religious and secular literature and ancient megalithic construction and ground drawings around the world.
Please submit only sites dealing with the Ancient Astronaut Theory. This is not the appropriate category for sites dealing with UFOs in modern times (20th century sightings, abductions, Roswell, etc); however sites pertaining to ancient UFOs could be submitted to this category, e.g. UFO reports in the ancient sectarian and secular literature.

Also appropriate here are sites addressing the nature of the "gods", their activities on Earth, and archeological sites if related to these ancient astronauts.
