ATHEIST ASKS SUPPOSED UNANSWERABLE QUESTION: DOES GOD CHOOSE TO DROWN CHILDREN?

An Atheist recently made the claim that he could ask a question that no Christian could answer. In fact, the claim was that God was a Moral Monster for drowning innocent Children in the Flood.
MY CLAIM IS:
1) The Question proves God Exists!
2) The Kids were the ONLY ONES TO ACTUALLY BENEFIT FORM THE FLOOD. Say WHAT?
3) And THE ATHEIST asked a NONSENSE Question PERIOD.
