Scientists wouldn't claim it to be a "law" either. They would point to Newton's
Theory of Gravity, for example.
However, the relevant point here is that the various physical principles, call them theories or laws, were created along with the universe. Physics is exploring the concept of multiple universes, each with different properties: they may or may not exist alongside our own, and only a fraction may be stable.
We happen to be living in a universe where the physical principles allow not only for a stable cosmos, but for life to exist: this is a wonderful thing.
If there is or can only ever have been one universe then this is also astonishingly unlikely.
If there are, or have been a succession of, many universes, then the fact that we are here to observe the existence of a universe with life in it serves to filter out all the unlikely ones: obviously the one we ended up in was stable and could support life, because here we are! (This is an example of what's known as the Anthropic Principle.)
