Evolution is both a fact and a theory.
Evolution as Fact and Theory
NAS: Why teach Evolution?
I hope this clears up the confusion. Notice the discussion in the last link of what "theory" and "fact" refer to in science. If not here is my statement on this.

- Biological/organismal evolution is both a fact and a theory. The fact of evolution is that the properties of populations and lineages of organisms, or frequencies of such properties, change over time. The theory of evolution explains this observation by identifying mechanisms that are responsible for it. Such mechanisms include mutation, natural selection, genetic drift, and isolation. Evolution operates on and is observable in populations.
