It’s just a conjecture I read back a while, so I cannot address your questions.
I’m okay with a literal reading of Genesis 1:1. Physics tells us that even time had a beginning, so there was no chaos in existence to order, unless we are talking about after the big bang. By definition, God is uncreated. There are several NT scriptural passages that are relevant…
Through him all things were made, and without him nothing was made that has been made.
John 1:3
