Oh man, I thought we were beyond the Zeitgeist movie by now. Even as an atheist this movie with its lack of scholarship bugs me. It tries too hard to Hero With a Thousand Faces tie up religions with a neat little bow, ignores contradiction and even fabricates resemblance(or, at least, imports fabrication from Archaya and the astounding lack of further citation). For example there is no actual account of Horus's purported 12 decouples, wise men, baptism et all. And rumors of 'virgin birth' is taken from Isis throwing away her husband Osiris' penis, neglecting that she fashioned him a new one and humped him to conceive Horus.
Further, because it uses such narrow sources, and very little first hand accounting, it completely leaves out other more probable mythological origins like older Sumerian cultures and yes, even some original myths to the region.
It's basically a lazy parse of the discussion.
This particular reupload of Zeitgeist also amusingly leaves out the rest of the movie which goes on to insist 9/11 was a government inside job with the same Loose Change style arguments that have been roundly debunked. So that's the kind of people you're dealing with when addressing the makers of this movie.
