Evolution is still just a theory and therefore not an exact science.


About 99% (just a guess) of all science is a theory. After a theory comes a law. Very little is considered a law in science (Second Law of Thermodynamics, etc). So virtually everything you do or know from science is from a theory. A theory is very close to a law (in most cases). So things that are considered a theory are usually true in virtually every test and can be "as good as" a law.
