The issue you're running into is a pretty common one, and it's essentially an issue of confusing the common meaning of the word with the scientific one. "Theory" in this sense is a scientific term, it doesn't just mean a possible but not certain explanation, as it does in common language. In science, a theory is seen as just as valid as a law, but they explain different things. Essentially, a law says THAT something happens, while a theory explains HOW it happens. Evolution is the explanation of HOW organisms change over time, so it's a theory. So yes, it's fact, but it's also a theory in the scientific sense of the word.2

Evolution is both a theory and a fact. Gravitational attraction is a fact. And the theory of gravity is just that --- a highly successful theory.9
