In the interest of being fair-minded, I thought I'd point you toward this interesting article, which suggests that one's "capacity for transcendence" depends on the level of one's "concentration of serotonin receptors." I don't really know what that means, but the last paragraph explains it, I hope:
[T]he researchers see the evidence as contradicting the common belief that religious behavior is determined strictly by environmental and cultural factors. They see a biological underpinning for religiosity, and it is related to the neurotransmitter serotonin.
So there you have it. Science trying to explain Religion. Interesting, if nothing else.
