Proving a theory or an idea can-not simply be done by destroying all questions around it. It must have a proof to exist by it's self. Besides, maybe by falsifying a theory you may actually get a piece of it wrong. You can't simply go zapping out large brain tanks without showing a little proof. The thing i'm trying to say is that by "eliminating" one theory, it chain-reacts into destroying other theories.
Like if you were to falsify creationism or evolution, what would happen to the universal clockwork theory? It would have to to be scraped.
