Evolution is a fact in the sense of it being overwhelmingly validated by the evidence. Frequently evolution is said to be a fact in the same way as the Earth revolving around the Sun is a fact.[15][16] The following quotation from H. J. Muller, "One Hundred Years Without Darwin Are Enough" explains the point.
There is no sharp line between speculation, hypothesis, theory, principle, and fact, but only a difference along a sliding scale, in the degree of probability of the idea. When we say a thing is a fact, then, we only mean that its probability is an extremely high one: so high that we are not bothered by doubt about it and are ready to act accordingly. Now in this use of the term fact, the only proper one, evolution is a fact.[3]
The National Academy of Science (U.S.) makes a similar point:
Scientists most often use the word "fact" to describe an observation. But scientists can also use fact to mean something that has been tested or observed so many times that there is no longer a compelling reason to keep testing or looking for examples. The occurrence of evolution in this sense is fact. Scientists no longer question whether descent with modification occurred because the evidence is so strong.[17]

So you disagree with this? If so then you're no scientist and you shouldn't call yourself one.
