Fermilab and CERN are currently racing to see which lab can be the first to verify the discovery of the Higgs boson. When this happens, another big piece of the puzzle will have fallen into place and your case will suffer another blow. The mathematics behind 10-dimensional superstring theory have also been proven. The mathematical soundness of a proposal is not the same as physical evidence of an event's occurrence. Mathematics enable the theories to make predictions which can then be confirmed by experiment and observation.
Mathematics can also point out deficiencies in existing theories.
For example, the mismatches between mathematical predictions and observations of planetary orbits led to Kepler's laws of planetary motion and to the modification of Newtonian gravity by Einstein's general relativity theory. All of this points definitively towards an origin of the universe which is knowable, understandable, and natural in all respects. No, all that points definitively towards is the absolvement of mathematical equations which are associated to unproven theories. With complex questions, it is necessary to build the answers in many individual parts. It's similar to constructing a large building.
