Actually, it is. Although with the wailing and knashing of teeth over this issue it really hasn't been discussed in that manner very often. Although you've been around these threads long enough, I'll be you've seen this, but pretend you haven't.
It is clear by studying the evidence that evolution occurs. Therefore evolution is a "fact".
However, like gravity, evolution is a description of a phenomena, and therefore it is a "theory" as well.
Like the "theory of Gravity". Or the "theory of Music". Both of which exist, and are "facts". But are also "theories".
Many on the scientific end of this discussion go to lengths to point out how evolution is a "theory" and as such is actually at a higher level than "facts". But they often neglect to point out that evolution is fact as well.
Charles Darwin wrote in his book The Origin of Species that one of the greatest objections to his theory were the gaps in the fossil record. Those gaps are still there. The fossil gaps between families and the higher classifications are both so large and so persistent that some evolutionists have even invented a theory to explain them away called punctuated equilibrium. The theory is that change in animals in the past was so quick that it left no record of its happening. This truly is the perfect theory; the proof of its happening is that there is no evidence of its ever having happened. The more that these evolutionists find no evidence of change ever having happened, the stronger their punctuated equilibrium theory gets, at least to them. There is a real Alice in Wonderland logic to it all.
Luckily I'm not too busy this afternoon so I'll play along. There are scientists who don't agree that dinosaurs turned into birds. There are those who question what the Cambrian explosion means to evolution. Of course, I think we all agree that life adapts to certain conditions. As for speciation, I don't believe all agree at this point.
