Torturing children for fun - is that absolutely wrong?

The Moral Argument for God states that there are such things as objective moral facts, and that objective moral facts must have an immaterial source - namely God. Therefore God Exists… Simple right?

However, atheist Cambridge Philosopher Arif Ahmed disagrees with the first two premises. He debates with New Zealand’s Christian philosopher Glenn People’s on whether the argument proves the existence of God.

So, are moral beliefs nothing more than our “preferences”? What do we do with the intuition that certain things are absolutely wrong? Are atheists who affirm moral facts but deny God, being inconsistent?
