It should be taught in school, but with the emphasis that it is a theory, not indubitably true. This is absolutely crucial to instill into future scientists of all sorts; science deals with PROBABILITY not absolute CERTAINTY purely due to the problem of induction. The future generations should not be swayed into believing that science is the 'end all, be all,' in terms of considering it as absolutely certain knowledge; it cannot be, science was not founded upon that sort of foundation! I simply want science [specifically hard siences] today, and for the future, to be humble and respectful of other disciplines such as philosophy, sociology, psychology, ect. and realize that it does not nearly have all the answers. I feel that hard sciences like, physics, biology, and chemistry enjoy dismissing the soft sciences, in addition to philosophy, as a bunch of BS that does not really give us any new knowledge, when the truth of the matter is neither can the hard sciences lay claim to any true proof/evidence for anything, rather it can merely ask "how" questions, not "why" questions. The other disciplines do in fact contribute to the knowledge base in a plethora of ways [e.g. medical care, ethics.morality, politics, ect.] EDIT: Before replying and demonstrating your ignorance by saying something like; "X is a real thing," or "there's no contradictory evidence, therefore it is a fact." Understand first that science ONLY concerns itself with probability and efficient causality [it may only answer "how" questions]. In order to claim something is an eternal indubitably certain truth, one would have to empirically observe something indefinitely to verify its truth, this is quite obviously impossible. The future is yet to be and the past has already been, therefore there is no absolute guarantee of anything to be the case because there is ALWAYS a chance that it may not be the case in the future. Surely, we will all agree that gravity is indeed present on Earth in this moment, but let me ask you; what is preventing it from ceasing to exist in the next moment? By what proof do you have to GUARANTEE that gravity will continue to exist on Earth a moment from now? You don't have any, all you may rely on is your previous lived experiences to provide you with a great probability that gravity will continue to exist on Earth in future moments. In terms of or discussion of evolution, there truly is no way to provide any proof for it, simply probability. Moreover, it seems to be a much lower probability than one might expect considering our short lifespans, thus our inability to empirically verify the changes over the incredibly long time period that the theory rests upon.
