Tell that to people who try to tell others they are fools for not accepting evolution as truth.
You have scientific facts, that would include both the natural laws and physical objects like
fossils. These are facts, since only a mad man could deny their accuracy/existence.
Then you have scientific evidence. That would be observations that anyone can make, and
thereby verify. An observation could be fossils placed in chronological order, and then you
see a progression from one form to another. It could also be the result of an experiment
that is repeatable. A scientific piece of evidence is not necessarily a scientific fact, since
it's possible to misunderstand what you observe, or certain facts could be missing so you
don't get the complete picture.
Finally you have plausible explanatory models that must account for the above. It's this
model that allows us to test whether or not we have a decent grasp on the full picture
regarding a specific class of evidence. The point of an explanatory model is to expand our
understanding of reality, and hopefully discover new and interesting facts. It does this by
allowing us to make predictions and test whether or not those predictions come true. This
explanatory model is called an hypothesis initially.
An important part of real science is the peer-review process. The idea here is that you must
submit your hypothesis to the community for serious inspection. Other scientists whose
fields of science are somehow related to your hypothesis will examine it thoroughly. Their
goal is to find everything wrong with it, and if you (or anyone else) can't correct your model
to account for any contradictory evidence, you lose and the hypothesis will join that heap
of sad failures that's constantly growing.
However, should your hypothesis pass the peer-review process, and if there's enough
evidence to support it, it will be taken as a workable theory. At that point, though it's not a
scientific fact, it's considered to be an essential truth from which new hypothesis and
theories can be spawned. Some of those may lead away from the theory, in which case it is
again put into question, and the cycle continues.
Now, the theory of evolution has withstood serious peer-review inspection for over a
hundred and fifty years, and there's a massive amount of scientific fact and evidence
collected, all of which support the theory, none of which contradicts it (though creationists
attempt to argue otherwise, in the eyes of the scientific community they fail).
It's still a possibility that evolution is shown to not be a complete explanation, like newton's
theory of gravity was shown to not be complete, but it's worked so far as a model that can
account for all the collected facts, allow successful predictions and spawn new and
interesting fields of science. It's a very useful and solid theory at this point, and only
religious literalists yet oppose it.
