Its not a theory in any sense of that word.
Why not? It certainly hasn't been proven as scientific law by repeated experiments
All science is theory. Even mathematical "laws" are theory. This is the uncertainty theists struggle with and reject in favor of blind faith.
Scientific laws are simply theory that has been proven over and over and over and over and over and over...And all the chains in the theory are linked together clearly and provable at the same time. But scientists, practicing good science, are always willing to test all theories.
Radio carbon dating is a theory. And it is supported by mathematical law. And all the chains in the theory of radiocarbon dating are linked and provable at the same time.
The theory of evolution is a bit trickier. While all the links are provable at the same time they aren't necessarily connected well enough to be considered theoretical law. This is mostly because we don't have a good way to model the science of evolution mathematically very well.
