Science is the practice of reverse engineering creation. The pursuit of science is predicated on a distinctly monotheistic premise that the natural laws are reliable and they do not change.

Explanation
We learn physics as a set of mathematics that tell us how the world behaves. It is easy for someone to get confused and think that these mathematics define that behavior. No. The mathematics were worked out in reverse by observing behavior and using math to put together a useful way of explaining, categorizing, and predicting observations. It’s no different than getting a gadget, taking it apart, and trying to figure out how it works.
Deconstructing reality in the same way tells us how reality behaves, but it does not tell us why. The why is all just speculation until you base it on revealed Truth.
