A Proof From Evil For the Existence of God

Monroe

William Lane Craig presents an argument from the existence of evil for the existence of God. It looks like this.

1. If God does not exist, then objective moral values do not exist.
2. Evil exists. (Therefore, objective moral values exist.)
3. Therefore, God exists.

An atheist who objects that a good God would not allow evil assumes evil exists. But on atheism as philosophical naturalism evil does not exist. Therefore, evil actually proves that God exists. 

Craig writes: "If this argument is correct - and I think it is - it constitutes a decisive refutation of the problem of evil." Namely, not only does existence of evil not provide a reason for denying God's existence, it provides a reason for God's existence.

(Because, on philosophical naturalism [atheism] objective morality does not exist.
Because, on philosophical naturalism, one cannot derive 'ought' from 'is' [in spite of the protests of Sam Harris].)
