Nobody created God. God is eternal Being (i.e., Life).
Note the "eternal" word: In the first place, eternity means: God has no temporal beginning and no temporal end. No causation can possibly pertain to God on logical grounds because eternity does not pertain to the linear time succession that finite mortals experience in which events take place in the natural world. Causation cannot happen without space and time. But God is not "in" time; and certainly He is not restricted by space.
In the second place, God is the creator of the laws of the universe cognitive, physical, and moral. It is senseless to say that the creator of a system is bound by the system he creates.
BTW, we Christians do not believe in "sky gods." Maybe if you would stop thinking with your "noodly appendage" you could grasp this point.
I look forward to hearing from you, Filo!
Better than that .... What "Is" God?..
What is God that it can be created?..
Is it possible something can be beyond formulation?..
God's Name is I AM.
