You: Why is that one thing God? Perhaps you are wrong in the details and the one thing is Satan?

Aaron: If an all-powerful Satan existed, then God would not be perfect. In order for him to be perfect, he must be unmatched in power. For this reason, only he exists. All other applications of the proof are rendered invalid.

You: Again, how can you be so sure? I could trade Satan for God in your explanation and prove that only an all-powerful Satan exists. Why would I be wrong?

Aaron: Because you owuld be stating an untruth!

You: Perhaps, but my reasoning would be just as valid as yours. Where is the difference? Why is your argument for God superior to mine for an omnipotent Satan?

Aaron: You are wrong because I know in my heart that you are wrong.

You: What has that got to do with anything?
