Wired for belief?

To say that people believe in God because over time we evolved with a, "God center", and that those who believe tend to survive better is no stronger an argument than saying we survive better while believing because we are made for belief. What if widespread belief is whispering of a deep need in man? And since arguing for a, "God center", can not be proven and is ultimately just another belief, it is undercut by its own claim.
