[///An atheist says to a believer that they have an interesting idea there, but I want to see evidence as I don't tend to rely on faith, thanks. I can't dismiss your idea for certain////

That's not an atheist; that's an agnostic.

And an agnostic, having declared that he can't say for certain, can then go ahead and believe (just for himself) that there is a god. OR he can go ahead and believe (just for himself) that is is NO god. In either case, he can't prove it, and admits it--and goes further, that he believes that NO ONE can prove either proposition, even though he chooses to believe one or the other.]

Absolutely wrong, Dave. There is not a self-respecting atheist on the planet who can say for certain that God does not exist. Dawkins freely and cheerfully admits that he can't be certain that God does not exist. But there is no fence-sitting here. The reason I can't say for certain that God doesn't exist is the same reason as the one that makes it impossible for me to say that an orbiting celestial teapot doesn't exist. A proposition has been put that is utterly implausible but which can never be utterly disproven (the proposers make very sure of that). What I can say is that no evidence has ever been put for the proposition and, as a result, I consider that the possibility of its being true is vanishingly small, and, as such, it has no effect on the way I live my life. Agnostics are not like that. They admit that they are in a position of wavering. I think they need to get off the fence, but that's just me being intolerant. I hope I've explained that that is most decidedly not the position I'm in.
