Christian apologist John Cranman presents his version of the Moral Argument arguing that God is the best explanation of the existence of objective moral values and duties.
Atheist Cory Markum responds by arguing that, in various ways, God cannot ground objective morality. They both also debate whether objective morality/moral realism exists.
