Anyone who uses the "evolution is just a 'theory'" argument doesn't understand 8th grade science, which is where we are generally taught what "theory" means in science (hint: it doesn't have the same meaning as it does in common parlance)
Actually it's pretty close to the same. In science, a theory is when you have a bunch of facts and you try to explain them. For example, I notice the fact that creatures evolve. Evolution is a fact. Now I try to explain this. I come up a theory about random mutations, I could also put out a theory about natural selection, and I can make up a theory about gene shift. The theories are explanations for facts. While the facts themselves are never wrong, theories can be wrong. An example of a wrong theory is the theory of flogistin. Flogistin was a theory that things burn because they are releasing flogistin, the fire element. Things burning was a fact and is still a fact, but the theory of why they burned turned out to be wrong.
In common not-science use, that's basically what a theory is. Take a bunch of facts then try to explain them. It's perfectly acceptable for a theory to be wrong, but the theory must be based on facts. Let's take a fact like JFK is shot in the head. Another fact is that US-Cuba relations were bad at the time. One could put out a theory that these two were related in some way, the fact of bad national relations caused the fact of someone being killed. This is a perfectly good theory until it can be proven wrong or until a better theory comes along with more evidence. The lone gunman theory has more supporting evidence, so it is currently the accepted theory.
Evolution is a theory. Creationism is not a theory because it's not based on any facts. If there were some evidence that things abruptly appeared, then creationism could be a theory. It could even be a strong theory with a lot of support, but it's not. This dumb bitch is in fantasy land. She's so far off the mark that she isn't the type of person to wear a tin foil hat and say JFK was assassinated by Castro; she's the kind of nut who would ignore the facts we already have then conclude that JFK wasn't really shot and that it was actually a stunt double and that aliens shot the stunt double and there's no such person as Oswald. That's how far off she is.
