All I'm asking you for is your substantiating argument, fact, reference, etc. that grants you "knowingness".
From where I'm sitting, Occam's Razor is a better argument.
You stated that God was creating before he created this universe because, according to you there was nothing.
My point is that your whole premiss is wrong because If there was a God before the universe was created, then there was SOMETHING and if God existed before THIS universe was created that means that another universe ( or reality or existence, pick your poison) was already in existence.
You said God couldnt' know anything before the universe came to be created, but that God himself existed and, we presume, God is self-aware, then, since God was all there was before THIS universe was created, God would knwo all there is to know about Himself.
From where I am sitting, you postulated that God couldn't have created anything before the universe because there was nothing before the universe, which is incorrect because , according to your view, God already existed before the universe He created.
