Btw, to say "it will never be proven that Gods do not exist" is as faulty a statement as saying "Gods do not exist". Your statement is a universal negative that even includes the time dimension. You cannot know what will never be proven, and you cannot even adequately define the term "proof".
For me, the proof that a god doesn't exist is that there's no proof that a god does exist. The same is true for the flying spaghetti monster, his noodly appendages be praised. The mere concept of an omniscient deity dictates that it's existence be unquestionable to the rational person. The existence of the moon is unquestionable to the rational person, but we don't worship it. If a god cannot at least be as undeniable as the moon, is it really a god?
Sure the apologist will say an omniscient God could, by definition, remain undetected but then that's taking the exception and using it as the rule, like saying an omniscient God must remain undetected. Even still, if the God is undetectable, how do we know of it?
