"> God/creation doesn't solve any of the mysteries we still have left" "But saying that, "Since we then cannot answer the question of where God came from, God must not exist" is not logical." I see what you're saying, but I think GP may be arguing whether or not that is useful. For example, what does it say about God beyond that God exists? You ask some good questions, in particular what is the purpose of our life. D…
Whether it's useful is, of course, a matter of opinion and presuppositions. If one, for whatever reasons, thinks that there might be an afterlife, then nothing could be more important. > You ask some good questions, in particular what is the purpose of our life. Does the existence of a prime mover help us decide this? I think we need something more. That depends on whether you believe the prime mover has communicated…
I think you've hit the nail on the head here. This brings us to the question is how do you move from the existence of a prime mover to the belief that the prime mover has communicated with us. It's not clear to me that existence implies such communication. And if it doesn't, it's not clear to me that the existence of the prime mover in and of itself is doing any useful work.
On the other hand, proving that there is no prime mover is a well-known difficult problem as well :)
