For instance? And you can also tell me what science has proven regarding evolution? NOTHING!! So what did the church beat up a scientist with a stick over?
Science doesn't 'prove' things, rather, it attempts to 'disprove' them. Any theory must have some aspect that can be tested to see if it is falsifiable. All scientific theories are like that, including evolution. Thus far, evolution fits the observed evidence better than any other explanation and has not been falsified, nor is there a theory that can better explain the information observed.
