Well, yes, 1; God did create the universe-by defintion, there is only one (”universe” remember?), per Genesis 1 (”the heavens and the earth”).
2; Adding to what is written is a fairly common humnanistic error-to suit the man, not the Creator.
3; Absolutely no “proof” of your “unbidden” claim, refer to 2 above.... Action requires an actor and an object.

I respect your view, while thoroughly rejecting it after much study and effort.
Also, Jesus told you "In my Father's house there are many mansions".
