Point #2 is a very shaky one. There is widespread evidence in the scriptures for extensive editing and forgery after the originals were written. It is highly likely that "predictions" were inserted into the edited scriptures after the events took place.

Point #3 is hardly convincing. Speculation about the shape of the Earth predates the scriptures. I am sure that even the ancient Greek philosophers speculated about the water cycle (they speculated about just about everything else, and through sheer volume and persistence got it right sometimes). Now if the scriptures mentioned the cosmic expansion, the structure of the proton, or the existence of the double helix of dna, you would have a strong case, but it doesn't.
Noone can prove the bb theory. It is simply the best theory that we currently have to explain all the available evidence. There are many far fetched things we have discovered. Time dilation, collapse of wavefunctions, and dna transcription are but three, and they have all been proven correct. Why should the universe NOT have appeared from nothing. As I often labour on this site to explain,: the concept that the universe sprung from a random vacuum fluctuation is consistent with our unique status in the universe:

You are not a fool for believing in creation. The combined exertions of the greatest minds of all time
have not managed to prove that reality exists. If indeed it does not, then we may very well be simulations in a universe created by sentience that we may as well come clean and call God.
