Atheist: Do you even understand what logic is?
Me: Yes, I have a thorough understanding of logic: etymologically, historically, and practically. You?
Atheist (statement A): God is a failed hypothesis.
Atheist (statement B): Just because I can’t disprove God, is no reason to believe he exists.
Me: Pick one. God is an hypothesis, OR God is non-falsifiable. Both cannot simultaneously be true.
Atheist: If you were presented with absolute proof that God doesn’t exist, would you stop believing?
Me: Begging the question. The only thing that would ‘prove’ the non-existence of God would be for the universe to stop behaving rationally. In which case, even if I still existed, I could not believe in anything at all.
