I have not heard a convincing argument that true right or wrong can exists outside of a universe with a monotheistic God. Do you believe you morality is more right than a Nazis or a pedophiles? If so, you need a justification of why your morality is more ultimately correct and truly "good and better." I have not heard a convincing one that ultimately doesn't end in a monotheistic God. And if not, what are we even doing in this conversation? There can be no moral progress without an objectively better standard that we are attempting to discover.
