Rob,

Have to go soon, but I think it's important to make this last response as I believe it engages with many who claim non-belief is not belief.  I argue that, in the absence of evidence in support or against a claim, belief and non-belief are synonymous (in intent) as neither is capable of confirming or denying the claim (i.e. the existence of God/gods) they profess. Here's an analogy I find informative.  Two brothers are lying in bed and one asks the other where his slippers are. Boy 1 says, "under the bed." Boy 2 asks, "how do you know, did you see them?" Boy 1, "no, I just believe they are there." Boy 2, "If you didn't see them, you can't know they're there" Boy 1, "so you don't believe they are there?" Boy 2, "no, I can't prove they are there." Boy 1, "you can't prove they aren't there, so I guess you can only believe they are not there, or admit you don't know either way." I think this analogy shows my point well, either you "believe" God/gods don't exist or you are agnostic.
