hindu?

I simply don't understand how someone can choose a religion like that over something like christianity. They have over like 330 million gods and I think it's much simpler to believe in only one. I grew up my whole life with christianity so its hard for me to understand why they believe in what they do but I'm sure it must make some sense to them. In my opinion there isn't enough of a solid story behind the religion for anyone to believe in it but I suppose some are forced to believe.
