empirical science does not deal in proofs or truths, does not generate absolute or irrefutable models.
instead, empirical science deals in evidence, predictive and testable explanations, including falsification criteria, and is always PROVISIONAL.
despite what you have posted, this is as true for the SToE as it is for gravitational theory, tectonic theory, gas theory, aerodynamic theory, and all other well-established scientific models.
your erroneous statements have been corrected.
whether you have been corrected is your business.
