Actually no such thing as fact in the scientific world, only currently accepted theories (as opposed to hypothesis or ideas that are not supported yet/ever). These theories are useful in that they enable us to do stuff, understand stuff or lead us to other theories. Theories are never proven, only supported by results or experimental data. If you manage to disprove a theory, and this data/result is verified and agreed by the appropriate scientific community a new theory eventually takes it's place. Or a theory may be replaced by one which better models available data or provides for more accurate predictions (kind of an evolution of theories

So far nobody has managed to disprove the theory of evolution, which is widely supported by other accepted theories and data.
Now I'd be interested to know which accepted laws of physics evolution violates and why no one has made a big deal about it in the wider scientific community. You could be famous!! Or is it another case of BUZZ, you lose
Only in mathematics can something be 'proven' true although Godel had a bit to say about that concept being rubbish as well. Oh well, as long as the bridges don't fall down when I drive over them I'll be happy enough.
