Crispy78: This, I'm afraid, is nonsense. Atheism is a religion in the same way that 'not playing football' is a sport.
tinyE: I'm not saying I disagree with you but if I may be devil's advocate for a second (pardon the pun):
Does it or does it not take just as much faith to believe in something you can't prove exist than it does to not believe in something you can't prove doesn't exist?
Also on a lighter note, go easy with the sports analogies. XD Some people consider golf a sport. :P
The problem with that line of reasoning is it goes against the scientific method.
The theistic claim is that a god exists, by the scientific method such a claim needs evidence to back it up.
Something that you cannot prove doesn't exist also goes against the scientific method, claims need to be falsifiable.
The scientific method is usually where an atheist will come at the problem from.
I think a big part where these sorts of debates get bogged down is in the nuance between the terms 'belief' and 'faith'. These two are commonly used interchangeably when they should be separated and settled upon before debate. Generally for an atheist we have a belief, which is something we ask to be backed up by evidence. A theist has faith, this requires no evidence, indeed evidence can negate the need for faith.
I have found that a lot of the science talk us atheists use in these debates does tend to be a sort of trap, but not necessarily a bad one with the thinking behind it. It's generally refreshing to see a theist respond simply "I don't know, that's why I have faith." since this at least shows some actual faith in their faith (note: other atheists response to this will vary wildly. I tend to be rather nice and accepting in this regard, don't let someone like Aron Ra hear a theist respond like that! :P). Attempting to respond to the scientific questioning with science is the trap, it's made to show that their faith may not be all they think it is, one sort of misses the point of faith in trying to prove it scientifically.
