Nope. That's what scientists do. That's what scientific funding agencies fund, and scientific journals report, and scientific societies and academies support. It's what the word "science" means in English. You have your own definition, but it's not the one used by people involved in science.
I know. What I'm telling you is that your understanding is wrong -- it does not correspond to what real scientists do. You may not be able to test millions of years ago, but scientists can test, quite easily sometimes, hypotheses about things that happened millions of years ago. As long as there is physical evidence, science can be done.
Here's a tip: if everyone else uses a word differently than you do, the problem isn't with the other people.
Try learning about real science -- there are tons of resources on the web for learning about all sorts of things, which will give you an idea of what kind of evidence scientists actually use and how they use it. But you'll never learn anything if you decide in advance that you're smarter than all the scientists and can ignore everything they do.
