No one can believe something that is completely implausible or doesn't make sense to them. The problem comes when anyone assumes that that only goes one way.

For my part, I was taught that all the stories of creation in the Bible were to be taken as literal truth, and even as a child that made no sense to me. But it also makes no sense to me that there is no God behind the creation of the universe, who will be eternally outside the realm of science. (In the movie, Pi's mother says that science explains the world "out there," and religion explains what happens "in here," pointing to her own heart).

What I like about the movie is that it acknowledges — and even celebrates — that what makes sense to one person might not, and doesn't need to, make sense to another.
