The moral argument says that objective morality is evidence for the existence of God. Some even go so far as to say that without God, objective morality would not exist. Why would anybody claim that? Wouldn’t we still feel that people committing genocide and rape is reprehensible even if there were no God? Of course we would. But if the immorality of such behaviors is to be an objective truth that is independent of what we think, then something besides us has to say people shouldn’t behave this way. There has to be some kind of transcendent, fundamental reality that says how we ought to behave. And this transcendent fundamental reality, I argue, is what we call God.
