Why don't biologists do what us physicists do when a theory becomes almost universally accepted due to the vast weight of evidence and start calling the previous theory a law. Examples in physics are numerous; The second law of thermodynamics and The law of gravity etc. Technically neither are really laws, just theorems (in the narrowly defined sense understood by scientists).
So come on all you biologists - start calling it the Law of Evolution and the Law of Nartural Selection and avoid all the tedious discussions with YECs on how Evolution is only a "theory".
