Earlier quoted context omitted.
Does it matter? Based upon the poster I responded to, it appears to be only the belief that's important, not the being.
If such being does exist, then how could it possibly not matter? If there's an architect and we are the architect's creation, then how could our belief alone be the important thing?
So, on the existence of god, we have two possiblities: God does exist, god doesn't exist.
1. If god doesn't exist, then we're unhappy because we're displacing a false god as the center of life.
2. If god does exist, then we're unhappy because we're displacing a real god as the center of life.
In that discussion, god's existence in fact doesn't matter, it leads to the same outcome.
