Well I gotta say something about this, don't I?
God's existence isn't dependent on people believing he does or doesn't - that's not the point of why we decide.
There's something we can all agree on - God either does exist or he doesn't - that has to be true.
The questions that one has to ask themselves are; If he does exist and I don't believe it, what's the result? If he doesn't exist and I believe he does, what's the result?
