One interesting test of the opposing point of view is to ask how easy it would be to convince an person of greater intellect than yourself of its truth. In the case of religion I think it's very, very difficult.
I'm not saying you have to be stupid and credulous to believe the utterances of faiths, because, to my frustration, lots of intelligent people patently do believe them. (Rowan Williams, for one, is far more of an intellectual than I could ever be.) But it would be pretty easy to convince someone of low intelligence that everything was "made by god" - it's a simple, comforting, reasonable-sounding platitude. You don't need to provide anything in the way of supporting statements or evidence. Which makes it extraordinarily convenient.
A scientific theory, on the other hand, requires reams of research, peer-reviewed publication and sometimes even decades of debate and counter-debate before it is accepted. Which is extraordinarily inconvenient - as it should be.
This is my problem with stillstanding's attempt to redefine the argument as one of opposing beliefs, a re-drawing of the playing field which I simply will never accept. My set of criteria is not just "mine". I recognise the intellectual burden of demonstrating "proof" of a claim, and where this is not possible, of providing enough evidence to put the claim "beyond reasonable doubt."
It's a bit like setting these two scenarios against one another:
a) saying your house was broken into by Fingers McSmith, because he is a dodgy type who is always doing that kind of thing and his eyes are aso close together (belief)
or
(b) providing DNA evidence, motive and opportunity for a case against Fingers McSmith (evidence).
Neither "proves" he did it, but you're on a hell of a lot less of a sticky wicket with (b). The two approaches are in opposition, but are patently not "equal and opposite".
