And that the betrayal, murder and subsequent reincarnation of the god happened long before those Bible prophesies?
Just read about religions around in those days in that area. There were a lot of them, and the virgin mother idea appeared prominently in many far before and during Christ's time.
Which stories can you document regarding these claims and where? Or perhaps I am misunderstanding your post?
You'd find the book of Isaiah is pretty explicit about addressing prophecies about Christ in detail, of which 600-700 years later were in fact fullfilled totally. And BTW, Christ wasn't "reincarnated", but was "resurrected."
