I think that it's also important, very important, to remember that the Gospels we have were written and re-written and added to and taken from, not only during the early years but since then. And if, during a period where gods and goddesses were dominant features of the religions, then the assertion that YOUR GOD was just like THEIR GOD because YOUR GOD did the same sort of things as THEIR GOD.

Besides, how many resurrection/rebirth myths can you come up with, especially if your experience and knowledge is limited by and affected by the religions around you?
