You can prove evolution to the same point you can prove creation. The real issue is you dont have to have a creator in the evolution theory and you use that to say hey this is science. But if there is creator you say not science because you have to prove the existence of a supreme being. When in all actuality none of the evolutionary theories have been proven so I think that you can take a scientific approach to any theory.
