Perhaps when scientists add all kinds of other theories and ideas, their model will change. They do have some serious science fiction there, or a religion if they believe it in the face of it not having been proven true.

I agree that the model will change. That is almost a certainty astronomy is not my area of expertise but it takes very little digging to hit the limits of human understanding. For example a few years ago scientist realized that according to the readings we have the universe is expanding at an increasing not a decreasing rate. However, we did not have any logical explanation for this so we made up one "dark energy" does it really exist or is the model wrong. I suspect the latter but it is the most widely accepted model currently.
However, a lot of smart people have worked on the model and while it is almost a certainty parts of it will change it is also possible that other parts will stand the test of time. Personally I see no conflict between the model and Genesis but that is not an interpretation that everyone will share.
The early universe, from the Quark epoch to the Photon epoch, (The universe was opaque or "foggy" as a result. There was light)
And God said, Let there be light, and there was light.God saw that the light was good,
followed by the "Dark Ages", from 380,000 years to about 150 million years.
and he separated the light from the darkness. 5 God called the light day, and the darkness he called night.
When the photons were released (or decoupled) the universe became transparent
And there was evening, and there was morningthe first day.
