“Science does not prove hypotheses/theories to be true, only that they are false. The best it can do is provide evidence that is consistent with a theory but this does not prove the theory to be true. The same evidence could be consistent with some other theory. Evidence that is consistent with two (or more) theories does not provide a basis for choosing between these theories. However, evidence that is inconsistent with a theory demonstrates that it is wrong.
Science is all about doing repeatable experiments and not everything that is billed as science qualifies. Dr James Gunn is quoted in an article in Science as saying, “Cosmology may look like a science but it isn’t a science. A basic tenet of science is that you can do repeatable experiments, and you can’t do that in cosmology.” In the same article, Dr Michael Turner, a theoretical cosmologist says, “The goal of physics is to understand the basic dynamics of the universe. Cosmology is a little different. The goal is to reconstruct the history of the universe.””
