From Wikipedia, the free encyclopedia-
"Certain (theorists) hypothesize that intelligent extraterrestrial beings called ancient astronauts or ancient aliens have visited Earth, and this contact is connected with the origins or development of human cultures, technologies, and religions. A common variant of the idea include proposals that deities from most, if not all, religions are actually extraterrestrials, and their technologies were taken as evidence of their divine status."
Some of us believe this to be true...religiously.
