Who said it had to be scientifically proven? Behe's claim is that it is theoretically impossible, and clearly that is not the case. "Since biochemistry darwinists have to work and to prove now!" - This sentence doesn't even make sense. It is Intelligent Design advocates like Behe that are making the claim that these systems "could not" have evolved. As another commenter said, this is the 'Argument from Ignorance' : "We do not know how it evolved so it could not have!". We know the structure of biological systems in more and more detail. We know how they change at the smallest level. The theory is fairly basic : redundant, self-assembling, flexible systems can change through gradual evolution. Gould would talk about 'rewinding' the tape of history. There's no way to go back in time and see for sure what previous systems looked like. However that in no way means the tape itself does not exist.
