Proving God Existence

[Muslim Scholar]

I didn't say that God is a physical object (actually he cannot be)

Creating the universe out of what is something beyond our knowledge, we only know things by approximating them to what we observe in our Universe
Creating the universe is something that we can never understand.

Well you just said something cannot come from nothing, god is not physical and has nothing existed before god created it (due to your definition of time, two events relating to one another).
You said even god cannot do something that is against logic and that something coming from nothing goes against logic therefore god could not have created the universe because he had nothing to create it from.

Correction!
Nothing existed before God because God didn't have a start
Nothing "Variable" could exist with God as well in the begining
This logic doesn't deny the existence of other things with God as long as they are static/constants
