the bible is a metaphor, and if u read it with an open mind u can learn a lot. but if u take every crazy thing that happens in it literal, everyone in the world would have been stoned to death by now for random sins.
..
and the purpose for jesus is (what was said in the da vinci code, and makes sense to me) to have the "keys to heaven." everyone wants to go to "heaven" so if u have a story in your religion that will get them there; a lot of people are going to want to learn about it.
