Science has an empirical aspect that you're ignoring here. Our theories are tied to nature through experiment. They are more than just inventions of the human mind. People come up with new ideas about nature all the time. Most of them are wrong, and we find that out by doing experiments.

Yes. If we take a look at social sciences struggling with experimental method, we'll see, that they get better with time. When experiments do not work, people somehow figure out how to do experiments better, and it changes things. It gives a hope that experimental method could falsify itself, so when it stops working we will be able to notice it. So if we do not see it to fail, we could assume that it works.
