To summarize your post as I understand it:
“Big Bang” vs “God spoke the universe into existence” is a false dichotomy.
The two views are consonant rather than mutually exclusive.
Thus supporting my lifelong contention that it takes as much faith to believe that the universe spontaneously created itself out of nothing as it takes to believe that God created the universe.
No, the Big Bang requires an infinity inside of creation. The only infinite is the Creator himself, outside of His creation.
What appears to be the Universe very close to the beginning of this cycle resulted from a phase transition as God said, “Let there be light!”. The Universe was already very big and very “old” at that time, but it was only about 15 billion years before “now” as we measure time in our local level in space-time.
Only differential theories can be deduced from observing the behavior of the universe. The Universe requires that boundary conditions be set for it from the outside, by the creator. The only way for us to know anything about those boundary conditions is for the Creator to reveal them to us.
So you are looking for a document that has been written down over a long time in human history, that is internally consistent, and contains an explanation of Creation, and predictions of things before they happen, so that when they happen you will believe the Word of the Creator.
Thus supporting my lifelong contention that it takes as much faith to believe that the universe spontaneously created itself out of nothing as it takes to believe that God created the universe.

One question then ... what is the unit of measure for faith, and what is the instrument you use to measure the amount of faith it takes to believe one thing over another?
“The Big Bang” is a science-dumbed-down-for-us-layfolks term used by scientists to describe the origin of the universe. If I asked a priest to describe it, he might say “God said let there be light”. I mean, if you asked a scientist to describe the events of “let there be light” to the layfolks, wouldn’t an apt description be “there was a Big Bang”.
Same event, different perspectives, different descriptions.
