This is one of the anti-evolution arguments that annoys me the most, so I'd just like to take a moment to set something straight:

The scientific definition of a "theory" is not the same as the colloquial meaning of the term.

What most people mean when they say they have a theory is more like a scientific hypothesis, which is basically an educated guess. Once enough experiments have been conducted that back up the hypothesis—or more accurately don't disprove it, because the point of a proper scientific experiment is actually to disprove its hypothesis—then it may graduate into a scientific theory, which means it is recognized by scientific consensus as fact. Unless, of course, something comes along to disprove it. It's always possible. But once an idea is recognized as a scientific theory, that means the vast majority of evidence supports it, so it's really not very likely to be disproved.

Note that a scientific theory is not a step below a scientific law. They can both be referred to as scientific fact—they just describe different things. Gravity is a good example of scientific law: if you jump off a bridge into an abyss, you will fall due to the effects of gravity. It is what happens, and you can't disprove that. Now, how gravity works, that's covered by scientific theory, which can be modified or even disproved with enough evidence. Laws are what happens, theories are how they happen. Evolution, therefore, is both a law (changes to a species happen due to various factors over time) and a theory (adaptation, natural selection, genetic mutations, etc.).

So please, if you must argue against science, whatever you do, at least don't make THAT mistake. It's annoying, and it makes you look stupid.

(Not YOU, [Evil AI], just in case that needed saying. I know you were just stating what the argument said. I just wanted to explain why it's a bad argument. {= ) )
