No, a scientific theory is not considered fact.
A scientific theory is an idea or group of idea which have been repeatedly verified by evidence. It seems there is often confusion between evolution (which is an observed fact) and evolutionary theory (which is the repeatedly verified theory that explains it). Sometimes, there's also confusion between the fact of evolution, the theory of evolution, and consequences of evolution such as common descent. They are three different things.
Evolution is merely a change in allele frequency in a population over time.
I am not confusing "theory" with "hypothesis."
You seem to be confusing the phenomenon with the theory that explains it.
"Theory" is the best and most accepted explanation.
Not quite. A hypothesis cannot be a theory until it has been repeatedly verified by evidence.
I can see how you can be confused that it is considered a fact. It is not, however, a fact. When that "theory" is proven true, it is a "fact."
Nothing in science is "proven." We can only have logical certainty when we have all the rules and can apply them as needed. In science, we look at the particulars and infer the rules. It's therefore inductive, not deductive.
But it works. Works better than anything else we can do to understand the physical universe.
You know, and I know that evolution will not be proven true in our lifetimes. Therefore, it is not a "fact."
It's directly observed to happen. Can't be much more of a fact than that.
