Without entering into a vast digression, Noether's has been used as a tool to DISCOVER symmetries/conservation laws, not to explain them. We then went out to the real world, with physical instruments and observed that the predicted relations actually held. Math doesn't explain why things are, nothing does that. It simply shows us structure, relations which hold, and gives us proven tools which actually work. Sure, some alien, or the mathematician down the street, can invent some other model. That's irrelevant, all these models, the successful ones, invariably turn out to be restatements of each other. Just like the Hamiltonian Mechanics is exactly equivalent to Newtonian Mechanics, though it can be more tractable in many cases.</blockquote>
