True, if there was intelligent design, it lies in the Laws of Physics. Everything else, however, is evolution, IMO.
When God created the universe he needed some kind of structure to it. If He didn't then we would have chaos. One interesting thing about the gravity constant. If it was a just tiny fraction more or a tiny fraction less we would not have the universe. I don't think that was happenstance that the secularist believe.
It's certainly possible. The Big Bang may have been the result of the Big Man, but all the rest is all evolution, right?
You know that TBB is just a place holder, don't you? A place holder to explain something that can't be explained.
No scientist alive can tell you what was here before the BB, what energy initiated the BB or where the energy from the BB came from.
They also can't explain how the BB happen within the Laws of Physics as we know them.
However, to answer your question. The universe in general and microcosms within has changed over time. I think that is pretty much a given.
