Evolution is often described as a fact, and a theory. Evolutionis a heavily overloaded term, with one definition being the factthat, "changes in the frequency of alleles in populations oforganisms from generation to generation." This is a measurablefact, but not the usage of the word evolution that I am ininterested in.

Wikipedia has several quotes on the matter, including theWebaters definition used in this questions title, but also includesclearly observational facts like the Earth revolves around thesun.

A fact is a hypothesis that is so firmly supported by evidencethat we assume it is true, and act as if it were true.
