Very clever. You have contrived a definition of atheism that allows this argument to make sense. And while we're contriving definitions when I used the word "clever" earlier, I may well have been using it the sense of cheeky and slippery rather than logically rigorous or convincing.

Assuming God knows He is God, then he, by definition, believes in Himself. Ergo, can't be an atheist.

With such a disastrous track record he couldn’t possibly believe in himself! Perhaps some CB therapy might help him get through this challenging period in his existence.

"We will ASSume....." uh huh

An Omnipotent and Omniscient being would have no need for an imaginary friend, therefore such a being would be an Atheist.

First you have to give objective evidence that a god is real.

Cute. If there is a God, then God is an atheist in the sense that he is not a theist because his omniscience is beyond any need for belief or faith in himself, let alone in a non-existent preceding creator God of God. But, this is only because the concept of theism only applies to mortals, not to divinity. Semantically true perhaps, but only because the concept of theism does not apply to God. One could also point out, for example, that a mortal atheist is not convinced that God exists, whereas God is convinced that he himself exists. Also, a mortal atheist is incapable of comprehending God, where God being omniscient comprehends himself completely. This is really an exercise in the ironies of the concept of God. This is why I am an ignostic. The very concept of God leads to a tangle of mental knots from which there is no escape.

A God that doesn't believe in God. Interesting concept.

Well, originally, the god of the Jews believed other gods also existed. It did not start out being the ONE AND ONLY GOD..that came later.

Um... I guess so. Using your own definitions you can make any statement true. Also, why can’t God create himself?

You say, " We will assume god is all-knowing. Therefore god will know there is no other creator than himself. "

So, "God" would be all forces of gravity, kinetic energy and chemical reactions?

Let's look at: create
verb
bring (something) into existence.
"he created a thirty-acre lake"
synonyms:generate, produce, design, make, fabricate, fashion, manufacture, build, construct, erect, do, turn out;
bring into being, originate, invent,initiate, engender, devise, frame,develop, shape, form, mold, forge,concoct, hatch; 
informalknock together, knock up, knock off
"the sculpture has been created out of Portland stone" When a Male and female do the reproductive activity, this causes a new being to come into existence. People are creators when making babies.

Often, create is used in context of bringing something from nothing like the big bang myth would speculate. I am not discussing that version here.

Hydrogen, they say is fused in the gravity pressure of stars to build larger elements like helium and the rest of the known periodic table of elements.

When ever a new helium atom is made by fusion it would be a new creation. Not that helium is new but that specific atom is new. The Sun and stars then could be looked at as Creators.

Continue with chemical reactions that bring about compounds that support what we call life having complex cell structures. Each one may very well be a simular copy of another yet they are each created and unique.

Creation by combining by use of forces is all around. Almost omnipresent maybe.

From the ancient-Hebrew.org reference: #1.
The Positive and Negative nature of Elohim
When I speak of the positive and negative nature of Elohim, I am not speaking about a "moral" positive and negative, but the "forces" of positive and negative, much like the two poles of a magnet or the forces of the protons (positive) and electrons (negative) of an atom. God is a perfect balance of positive and negative:
#2. Ruach is force, something with kinetic energy. Its base meaning is "moving air" — whether in the form of breath, a breeze, or violent storm winds.

So, what is written about Ruach of Elohim, or in English "spirit of God"?

Are you saying that she lacks belief in her own existence?

Well it doesnt exist, so TL;DR.

I like you. You make me laugh.

you have made a case for jesus, who may or may not have existed, not to be christian, which most of us know, but it's amazing how many christians seem to think he was (if he existed) a christian. he didn't follow himself!

but you have made no case for god's being an atheist because, unlike jesus, who probably didn't exist, god almost certainly doesn't exist, and i only say almost to accommodate the agnostics among us. therefore he not only isn't an atheist, he also isn't a teacher, a plumber, a stamp-collector or an alcoholic, among other thing he's not, because he's NOT. so he's not an atheist, but why pick on that one feature of his nonbeing, since he's not anything else either?
