The existence of God or otherwise here is kind of irrelevant, because even if we had proof of the existence of God it still wouldn't be clear what we should do about it - should we sing hymns? light incense? sacrifice goats? wear funny hats?
I can prove the existence of the Sun, but it's mere existence isn't enough to make me want to worship it.
I completely agree. Atheism and strict deism are virtually indistiguishable from a philosophical perspective. I never involve myself in arguments about whether a god exists. I completely concede the possibility of a god's existence, assuming the idea that something can exist outside the realm of existence has any meaning at all.
http://en.wikipedia.org/wiki/IgnosticWhat I do argue is that whatever god may exist is utterly irrelevant to our daily lives, and does not interact with our universe, at least in ways that are measurable or meaningful. Miracles and supernatural revelation have no place in our (admittedly limited) understanding of reality.
