@Bones-O,
perhaps this has been mentioned already, but God exists in the sense that a belief in God affects the way one thinks. God could be thought of as an idea that goes through memetic evolution, which is why the idea of God has changed so much over the generations. whether a creator or powerful being of some sort exists can't be empirically proven, but the fact that someone believes that God exists will make them behave and think differently, so couldn't one say that to them, God does exist in some form?
