GOD by definition is ETERNAL , TIMELESS. He always exists.
Therefore, to ask the question who created God, is to ask the question who created someone who always exists.
I contend that if you don’t believe in God, you are simply excercising faith as much as those who DO.
It takes no faith to not believe in something that cannot be seen, it merely takes sanity.
Belief in God is no different than people who believe in UFOs or Bigfoot. It takes blind faith without any factual evidence to believe in a God.
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 comet evil? Is he neither able nor willing? Then why call him God?
