Yeah I was going to say that...
Wikipedia said it best ..."Similar confusion is involved in objections that evolution is "unproven"; strict proof is possible only in formal sciences such as logic and mathematics, not natural sciences (where the proper term is "validated"), so this is trivially true, and no more an indictment of evolution than calling it a "theory" is. The confusion arises, however, in that the colloquial meaning of proof is simply "compelling evidence", in which case scientists would indeed consider evolution "proven". The distinction is an important one in philosophy of science, as it relates to the lack of absolute certainty in all empirical claims, not just evolution.[28]"
