All of science is that way. We know that it works and but don't know why. And since we know that it works,and very repeatably too, we can make things from it.

“We know that it works and but don’t know why.”

True, and we don’t know if it works everywhere the same way. It’s an assumption. When you know as little as we do about the mechanics of existence, you have to be satisfied with the explanations we have for what we can observe. It’s certainly better than knowing nothing, but ultimately we know infinitesimally little in the context of what is knowable.
