Islam owns atheism with a single verse

[Loaded dice]

LOL, 
It does, you are just too dense to get why. 
Theism is incoherent because it's god had qualities which are definable, 
BEFORE the Creator creates anything. 

It's not clear that there is a before here. Maybe God was always creating things for eternity. 

You god is "good", before a creator creates or defines goodness. 
Your eternal god found it's eternal qualities BEFORE anything is created. 
The question remains. Where did the Reality your god found itself in, come from ?

Since reality includes God in this hypothetical, reality is also eternal, and so didn't come from anything because it always there. Reality never came into existence.

See, your question wasn't that hard after all, nor does it prove that theism is incoherent.

a god can't be the creator of the Reality itself exists in.

Yes, and that's not a problem. Because then God creating reality would be logically impossible, since reality includes God Himself. (God creating Himself is obviously a logical impossibility)

And Got not being able to do something logically impossible isn't a problem.

There you go, the entirety of your argument against theism just fell apart and vanished.
