You're right. they continue to learn. So whose to say after 10-15 yrs they will be supporting current theories. They use to classify Pluto as a planet. Now they don't.
I'd sooner trust what they have to say than anyone else...you think you know better?
Also, let's make sure you're clear on the definition of a scientific theory. A theory is something that's been continually tested over time and has yet to be disproved. It's not just some shyt somebody made up, it's withstood constant peer review scrutiny, and remains sound. Science is humble, in that even if you're 99.9% sure of something, you still call it a theory so it can be tested by others.
