What part of the scientific method don't you understand? It's been explained enough on these threads--science cannot "prove" anything! It works by building up a preponderance of evidence in support of theories. Theories are not "wild guesses" as some believe, but well-defined tools for getting an understanding of how things work.
Science can't prove gravity, electrons, water always flows downhill, or anything else! It can show that these are pretty likely or demonstrate a good understanding of what's going on.
But in spite of the constant reminders on these threads, and all the dictionaries, encyclopedias and other sources, we still get this constant, unremitting drivel that "evolution is not proved!"
In your case it is Hahaha! A hundred and fifty years of research and still no proof? What a joke.
Please tell me, are you getting all of your information from the creation pages? Are you totally ignorant of the methods of science? Or are you being deliberately dense to tweak people?
It really doesn't do you any credit to constantly ignore the methods and rules of science like this. Might as well ask the bible to predict the next race down at the track. Of course it doesn't do that!
Science has its own specific method of operating; it works on data, hypothesis, and theory. Proof is not in there anywhere. (Science may not always be right, but its usually safer not to bet the rent money against it.)
