The Universal Law of Gravitation (F=G*[m*M]/R^2) or any other theory for that matter can never be proven beyond a shadow of a doubt. If you wish to stay incredulous to all the research and data that supports such a theory so be it; you're methodology for discovering truth is primitive and flawed.
Evolution is exhaustively supported (just as the Universal Law of Gravitation). The mechanisms which cause evolution are still being researched quite extensively. There are MANY mechanisms that all play roles for the outcome we know as evolution. In the meantime revisions will likely be made as new evidence is uncovered.
So feel free to stay in denial until you see bacteria evolve into a monkey. Likewise stay in denial of the math behind gravity and of the revisions made by Einstein. Pass off the mathematical equations regarding electrical current and voltage. Ignore the periodic table and all other scientific theories for that matter. Just pick and choose the theories which conform to your preconceived notions so you can happily skip along your path of ignorance and denial while ignoring the overabundance of evidence and the obvious direction it points. After all, the fossils and the DNA are just there to trick you.
