Does not the burden of proof then fall on the shoulders of the skeptic? Yes. And the skeptic is the first to admit this - or at least to exemplify it. I would hazard the view that more attention is paid to theism, religious belief, the existence of God, as a problem to be dealt with, as something that is an intellectual task, by the skeptic than by the believer. I have met many more militant skeptics than I have believers who look as if they were going to toss and turn all night unless they developed an airtight proof for the existence of God.
