The religious might claim to be using a priori evidence, though, so I think what you mean is empirical evidence. But doesn't that presuppose faith in the truth of empirical experience? To get through regular life, everyone requires faith (meaning belief without evidence) in a number of basic ways. I think the difference is that faith is basically pragmatic for the atheist, while for the theist faith can override reason. So it's for the theist that faith is superior to reason, while for the atheist faith fills the areas reason can't solve.
