Some ancient astronaut proponents such as Von Däniken and Barry Downing believe that the concept of hell in the Bible could be a real description of the planet Venus brought to Earth by extraterrestrials showing photos of the hot surface on Venus to humans. Proponents of the hypothesis state that 'God' and 'Satan' were aliens that disagreed on whether or not human beings should be allowed the information that is offered by the tree of knowledge. David Childress, a leading proponent of ancient astronaut creation hypothesis, compares this story to the Greek tale of Prometheus, who gave mankind the knowledge of fire. Ancient Astronaut proponents believe the biblical concept of Satan is based on a misunderstood visit by extraterrestrials. Erich von Däniken posited that the descendants of extraterrestrials had children with hominids, and this was referred to in the Bible as the "Original sin." Von Däniken believes that the biblical great flood was punishment after an extraterrestrial 'God' discovered that earthbound, fallen angels were mating with ape-like early humans.
