A theory cannot be "proven" until all axioms governing the universe to which said theory is a subset of are known.
What does this mean?
Yes, evolution, flight, relativity... Etc are true and work with what we know. However, what we know about our universe makes up about 1x10^-google of it. So no, we cannot say we have proven anything about science, because shit could change. Relativity kicking Newtonian physics in the nuts applies here.
You can, nevertheless, make a proof if your universe is, for sake of example, the real numbers. There are plenty of cool proofs that you could look up regarding them, if you so choose.
