You have to prove that your axioms are valid and true.

In this case your axioms are:
God is me.
God is omniscient.
God is omnipotent.
God has a penis.

The penis argument is not valid. As you are the one with the penis and god would not have one unless he was you, but you did not prove this yet. If you define god as a being which is omniscient and omnipotent then your arguemnt would be like this:

I have a penis.
God is omniscient and omnipotent
I am omniscient and omnipotent therefore i am god with a penis.

So if god has omniscience and omnipotence then you would have to demonstrate one of those powers in order to become god. You say that you cannot demonstrate such powers therefore you cannot prove that you are god.

You could be god, yet as long as no proof of your powers exists the idea remains hypothetical. So you are putting the carriage before the horse, it is not for us to disprove you are god, it is for you to prove that you are god.
