I doubt very many of us (and that includes Dawkins) are "certain" of our position. I'm certainly not; but I view it in terms of likeliness. In my opinion, the existence of any kind of afterlife is unknowable, and given that the various "revelations" of such places is based on nothing but hearsay and dogma, I don't think the case for such a place is very stable.
If I'm wrong, I'm wrong. If the God of the fundamentalists happens to exist, and I have to explain myself, at least I'll have the intellectual integrity to admit I was honestly skeptical.
