"Evolution is not a fact, it is a theory. There is a big difference."

Evolution is a fact AND a theory. Facts are not theories - they are different things, but neither are they mutually exclusive. You cite a reasonable explanation of theory. You do not give a definition or explanation of fact. FACT, in science, does not mean irrefutable. It does not mean 100% certain. It does not mean unquestionable. It does not mean directly observed or observable.

A fact is a bit of knowledge that it would be intellectually perverse to deny. We teach the existence of hydrogen atoms as fact, not because anyone has ever seen one, but because it would be intellectually perverse to deny their existence.

As creationists have a problem with intellectual integrity, depending as they do on mental sloth, they frequently accuse evolutionists of wanting to teach evolution as an unquestionable fact. That is one of their innumerable lies. Of course students and others are allowed to question evolution. Scientsts themselves who are actively involved in the research do not. But others can question.

HOWEVER, creationists themselves don't get blasted for "asking questions." That is a bald-faced lie. They get blasted for making stupid assertions, such as the ones made by anyman regarding radiometric dating. They get blasted for passing on urban legend as if it were fact.
