“Is God willing to prevent evil, but not able? Then he is not omnipotent.
Is he able, but not willing? Then he is malevolent.
Is he both able and willing? Then whence cometh evil?
Is he neither able nor willing? Then why call him God?”
― Epicurus

Or put another way: Omnipotence, Omniscience, Benevolence; choose any two. The very existence of evil excludes the possibility that there is God-being with all three traits.
