The stories about Jesus were myths copied directly from stories about Adonis, Tammuz and other middle eastern Gods. If you read much about Paganism and Christianity, you hear a lot about dying and rising Gods.
his stuff really got going back in the late 1800s, as part of a wider movement when a guy named James Frazer came out with a book called The Golden Bough Studies in Magic and Religion , which pointed out that in the ancient near east Gods like Osiris, Tammuz and the early middle eastern version of Adonis, had all died and been resurrected.
