Jim Davila at PaleoJudaica just shot a blast from my childhood. Anybody else remember Rod Serling hosting In Seach of Ancient Astronauts? It was an NBC-TV documentary purporting that many ancient mysteries (Stonehenge, Easter Island, etc.) could only be explained as the work of extra-terrestrials. The genius behind the explanations was Erich von Däniken.
Now, Jim tells us, von Däniken has turned his attention to the Old Testament Pseudepigrapha, where he sees abundant evidence of the patriarchs and prophets cavorting with aliens.
