Popular skepticism says that since evil exists, God is either non existent, impotent, or evil.
But if evil exists, we must have a standard of good that is beyond matter and energy to measure it against. Matter and energy only gives us what is, not what is good or evil. We would not know good or evil, only facts of what is the case. Therefore we either have to give up evil or accept a transcendent good. Even atheists such as Richard Dawkins admit that there is no good or evil if there is no God.
If God is evil, atheism is false, for God still exists.
If God is impotent, God still exists.
