Hothbanero, glad to hear you are not necessarily a "christian". That indicates you are open minded on the issues.
Yes hothbanero, a theory, known as the Standard Model of particle physics, derived around 50 years ago, predicted the discovery of quarks, the tau neutrino, and more recently the Higgs bosun. It is hard to overstate how important this is, in relation to our understanding of the universe. However, it was not the theory that had to be tested to a "beyond reasonable doubt" in each case. It was the results of the experiment. That is a very important distinction. In the case of the Higgs bosun, they had to get enough data to show that its detection couldn't be due to random chance, to (I am going from memory here) a 5 sigma standard deviation level, which is a small probability, well less that 1 in a million. (I could explain more precisely and in more detail, but I might get called a nerd again.)
The point is, it was not the theory being tested to beyond 1 in a million probability, it was the experiment.
Bringing that back to evolution, it is reasonable to ask whether some of the tests, experiments and data have been determined to a beyond doubt stage. Eg are we certain that DNA exists? How do we know carbon dating works? Are the fossils accurate reconstructions? Do jellyfish really have primitive eyes? etc. But that is not the same as proving an entire theory (the underlying explanation that appears to tie everything together) and every aspect of it, beyond doubt.
