Premise: Investigators circle the globe in search of evidence in their quest to determine whether life on Earth began in outer space and if aliens influenced mankind in ancient times. Did extraterrestrial beings visit Earth and share information about technology and influence human religions? And more importantly, if aliens visited the planet before, will they return? Alien theorists believe that the answer to both questions is a resounding yes.
Theorists speculate about metal artifacts that could provide physical evidence of extraterrestrials visiting Earth in the distant past; in Jacksonville, Fla. a strange metallic sphere falls from the sky; an ancient aluminum wedge baffles historians.
In Wiltshire, England, Rudloe Manor appears to be nothing more than an English manor house, but researchers argue it has been the epicenter of British research into UFOs since World War II.
