I enjoyed reading the different responses. I love this sort of topic, and love listening to people's varying point of views.
I think that any useful discussion on a topic needs to first establish basic definitions. I mean, it does no good trying to identify triangles unless we first agree upon a definition that explains what parameters constitute a shape being a triangle. I used this example from
Meditations, since the previous poster mentioned the belief in one's own existence.
Likewise, it becomes difficult to properly answer a question about "God" when there are so many possible definitions that we could use. Even if we assume the poster means a monotheistic God, since the word "God" is capitalized, are we also assuming an "all-powerful" being? What about omnibenevolent? Even if we assume that this God is omnipotent, could we be discussing a deistic version of God that starts existence only to indifferently watch it go whatever direction it wants after that?
Sorry, I am not trying to be obtuse. It just becomes a challenge to even address the question unless we have some basic parameters.
Still, fun topic.
