There is no evidence for "god", except some feelings some people have. The judeo-christian god in particular seems unable to transmit useful information to believers about what is the right way to believe and worship. Otherwise, how come can Judaism, different types of Christianity, Jehovah's witnesses, Mormons, syncretistic religions etc. co-exist? Why does "god" "answer" everyone's prayers in these different denominations in just about the same way? God does not seem to care at all about the details of religion, or alternatively he/she does not really contact people at all.
You will find that there is no end to the mental gymnastics used to get around arguments like yours. I expect that it will be argued that just because not everyone can have it right, does not mean that someone does not have it right, or that each religion does not have part of it right: God is not the author of confusion, man is.
That's well and good, but like most theistic counter-arguments, it ignores the elephant in the room. Occam's Razor dictates that the absence of evidence IS the evidence (evidence, not definitive proof) of absence when presence would require certain assumptions about the nature of reality, particularly ones that run contrary to valid expectations.
This is convenient to theists, who can move the goalposts as much as they like by defining what expectations are valid or not.
If I told you there was a can of coke in the fridge, and you didn't see one after a thorough search, you'd assume (tentatively) that I was wrong. If I told you that there was an all-powerful, personal God who offered only one way to heaven and had a habit of intervening in human affairs, you'd expect to see some behavior demonstrating this on a semi-regular basis (rivers of blood? plagues of locusts? flood geology? regular defiance of the documented behaviors ("laws") of physics and biology?), but we don't. So atheists like myself assume (tentatively) that there isn't a God and by the same token any mythical creature that has similar reality-bending powers.
It's possible that a can of coke exists in a secret compartment of the fridge, or that some miserable bastard put it in the freezer, just like God could exist in a way that defies our comprehension, but without something concrete to back either assertion there is no sense in even wondering about it. It's the same kind of mental masturbation you'll see repeated ad nauseum in discussions of comic book characters fighting one another; lots of pre-defined logic, lots of completely ignoring the fact that these are fictional universes that have zero basis in any kind of reality at all.
Atheism is a rational position, but it should be acknowledged (even you feel that it's practically a formality) that it's tentative. Science takes a "maybe, maybe not" approach with hypotheses, but favors the null hypothesis unless there is evidence to the contrary for the very reasons that have been discussed ad nauseum in this thread. Which I'm unsubbing from. Because we've gone over this a billion times. Ciao.
