God doesn't have need to bring Himself into being from non-existence, as God eternally exists... God is not a "thing" which exists because of some other "thing" happening or having happened. God has no dependency on any "thing" for God's own existence. God is neither "a being" or a "non being" Now, try and answer this very simple question: What has no opposite value?
God caused all things. God didn't cause Itself. God didn't cause all things. God caused all things. Creationist logic 101.
God is not a thing... God caused all things... Understand the meaning of a thing... Things are limited...existing in time and space (time and space also having limits) for a limited time and in a limited space, exist in relationship to other things, are created and can be destroyed...that's their nature. God is not a thing...God caused all things. God is one...things are many. God is whole...things are parts of the whole. God is totality...things are partiality. God is without cause...things are caused. God created all things out of Himself...
If god is everything and everything god then god has no existence. all you've done is to re-name all things (a rock, a tree, gravity etc) "god". a simple renaming provides no additional useful information about the thing re-named or 'god'. you are hopelessly trapped in a tautology
