Is this your point: somehow you believe this...
Genesis 1
1 In the beginning God created the heavens and the earth.
2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
3 And God said, "Let there be light," and there was light.
...is proof of the non-existence of God?
No!
What I've noted is ...
There is a contradiction in claiming that God exists in reality while claiming that God created everything -- including His own Self -- that exists in reality.
And what I've proved, thank's to that contradiction, is that the commonly identified causitive factor behind reality is beyond reality; that he, she, or it does not exist in reality; that he, she, or it transcends reality -- that God does not exist in reality.

That would be a silly contradiction, alright. Rather, it is appropriate to say that God is the uncreated Prior to all else (other than God) that is reality. That'll be $0.10. Blessings to see in the light.
