I have said it before and I will say it again: God's existence is contingent upon God's definition. Your 'proof' of God's nonexistence fails when we consider either pantheism or any of the finite theologies that have been proposed.

Please note that I am not attempting to prove God's existence in the present context. I am merely pointing out that, at best, you have identified an inconsistecy in one theory of the god-concept, ignoring all others, and having done so, you now claim to have 'proven' that the god-concept itself is invalid.

Now it may be true that the theology which you have sought to refute has enjoyed more popular support (in the West) than competing ideas such as pantheism. But refuting one among several credible theories explaining a particular phenomenon does not mean that the phenomenon itself has been shown to be illusory. To achieve that end, you would need to refute all credible theories--which you clearly have not done.
