First, you didn't explain anything. Science describes, it doesn't explain. Nobody has an explanation for why human-invented mathematics of motion, gravity, electromagnetism so perfectly describes and reflects the physical universe. That is totally unexpected and hints at a rational fabric underlying all reality which our rational minds can access.
Second, the physics of mechanics are not an 'after the fact' method of analysis. We can and do use the laws of motion to accurately predict the past. Give n enough information, that is precisely why we know when Halleys comet made a pass around the sun five thousand years ago.
The mathematical laws of physics seem to have an existence independent of spacetime and seem to exist in some kind of higher platonic realm. That is what the esteemed theoretical physicists Aleksandr Valenkin and Alan Guth say. I think that makes sense.
Correct.
