What you said is very true, you pin-pointed exactly why creationism fails so badly. You can't start with the "right" answer and never allow that answer to change. If that were so the universe would still be made of four elements (fire, air, water and earth) like the ancient greeks thought.
One point about what you said though (and I get the feeling that you already know this, so this is more for others who read your post). One tactic by people attacking evolution is to say that it is "only a theory" as if this is some kind of flaw or reason to think it is all wrong. I know this isn't what you were trying to do, but when I first started reading your post I thought you were.
For those who think that being a theory is a flaw, EVERYTHING science produces a theory. Einsteins theory of General Relativity is a theory, electromagnetics is a thoery, quantum mechanics is a theory, and evolution is no different to any of them.
In science, theories don't
become facts when they are verified. Facts and theories are not the same thing in any way whatsoever. Facts are simply things that are observable using the scientific method (ie repeatedly by anyone doing the measurements). Theories are models that explain those facts. More than that, they also have to predict future facts to be observed. If they don't do this then they're not falsifiable, as nothing you observe will ever be able to show them to be wrong.
So in short, being called a "theory" is not in any way an insult in science. If a scientist manages to produce a theory then he'll be very happy indeed
