Oh.. the experiment is proof.. but it isn't proof of what you are thinking of. It is proof that complex organisms don't spontaniously come togather right away... That , of course, would falisfy evoultion
The point you seem to miss is that according to the theory of evolution, changes in the organisms come slowly, and with random mutation
with the filter of natural selection allows for the increase in complexity.
So, you see, evolution is not 'random', but it does not require a 'design' either, since the natural process of choose those organisms that are better suited to survive to reproduce can allow organisms
form complexity over time.
Pointing to something and saying it is evidence is one thing. However, you have to back up what that 'evidence' means. The evidence you are pointing to disproves your thesis, and is not evidence for it.
