Then we know this theory is wrong and anti-biblical.
God is omniscient. There is no "finding out" about anything.
The purpose of the exercise is God divining if there is “anything that is not God”. This was the initial reason to create the absence of God, zimzum, a contraction, within God, then to use the beams of light, or lightning style bolt, to create the self creating mirror within.
“Is there anything not God?”, is the flip side of the most accurate statement God could make, “I Am that I Am”.
