When these people ask “Can God make a rock so heavy he cannot lift?”
The reply is “He already did. We call it the Earth”
They are starting with the false premise of *IF God can do anything (He wants to).....
Instead of debating that argument, the better way to defuse it is to point out the false premise.
God cannot do anything He wants. He cannot lie and He cannot change.
So that blows apart their premise to begin with.
