Science does not deal in proof, so the absence of proof is quite irrelevant. Science deals in explanatory and predictive models, based on observational evidence. Inference is a part of true science, so you are wrong there, too. (There is little excuse for you to be still making these errors about science. These points have been explained to you many times in previous threads. You seem to be just deliberately choosing to ignore them.)
Certainly there are theories that have been shown to be wrong, for example the phlogiston theory or the plum pudding model of the atom. However, more commonly, they are shown to be just poor models and replaced, at least for the relevant purposes, by better ones. An example in this category would be the Rutherford-Bohr model of the atom, or even Newtonian mechanics.
Evolution is a theory that fits a vast number of observations, is corroborated by several independent fields of science, and makes successful predictions so regularly that we don't even realise any more when we invoke its predictions. For example, we do not look for rabbit fossils in the Cambrian.
Equally important, there is no rival explanatory and predictive theory to account for the observations. So we use evolution for now, just as we use quantum theory, or any other theory of science, for now, until something with superior explanatory power comes along, if it ever does.
What is for sure is that "God did it" has zero explanatory or predictive power and as such is not capable, in any, way of being part of a theory of science.
