It really is a way to shift the demand. If I ever say "prove God doesn't exist" it is simply a way of showing the opposition that proof does not factor into the equation; if he can't provide proof, he should not ask me to.
I don't want to make this personal as a more general discussion is a lot more interesting, and also less likely to make people feel offended.
All religions make the claim that there is a god or gods. Chistianity most definately does too. However, when a claim is made, "There is a god", the onus is on the one(s) making the claim to back that claim up with evidence. How could it be any different?
Now, I am well aware that disproving the existence of god is impossible, just as disproving the existence of ANYTHING is impossible. In philosophical terms, that is called "proving a negative" and it is by definition not possible to do. However, since the claim in this context was made by the religious, the onus is on them to provide the backing for their claim.
Now, if an atheist made the claim "There is definately no god", not only would he/she have to back that claim up, but he/she would be a very silly atheist indeed. We simply cannot know with absolute certainty. But that doesn't mean that the atheist would consider it a 50/50 chance either. There are lots of things we don't believe in, or even consider ourselves agnostic about. I'm going to go out on a limb here and assume that no-one believes in faeries, but we cannot with 100% certainty say that there are no faeries anywhere. That doesn't mean that we consider there to be a 50/50 chance of there actually being faeries.
But, if someone was to make the claim that there -are- in fact faeries, then I suppose everyone here would want to see some kind of evidence for that claim before they believed the person making the claim, as well they should. In the meantime, until such evidence can be provided, we simply go about our day as if faeries do not exist.
Atheism is, in the broadest sense, the absence of belief in the existence of deities. Atheism does not claim that there is no god or gods anywhere, but simply that they do not believe in any.
