You: Because that would simplify nothing. Assuming that the universe exists uncaused solves our problem without adding the unnecessary complication of an all-powerful, omnipotent, eternal God.

Aaron: God is not a complication, but a liberating force.

You: He liberates us from the need to search for scientific explanations.

Aaron: No, I mean that he liberates us from the weight of our own sins.

You: I can see where this conversation is going and I don't think we have enough time to get into it. Perhaps you should concentrate on trying to demonstrate that God exists before you spell out the benefits of having him around.

Aaron: Of course.
