Well strangely a lot of things are "it just works that way," at least to our current understanding, like gravity, electromagnetic forces, things tending towards lower energy states. We could conceivably live in a universe where a ball doesn't roll down a hill, it just stops where it is and retains its energy.

I saw something called the "fine tuning argument" that said there must be some higher power because our universe could not exist without those constants being what they are, but we also wouldn't exist to experience it otherwise so ¯\(ツ)/¯
