Just like the greatest most eminent thinkers of their day knew Alchemy, Neptunism, the geocentric universe, Spontaneous Generation, Lamarckism, Emication, the existence of the planet Vulcan, Lysenkoism, Gradualism, Trepanation, Miasma theory of disease, Telegony, the expanding earth, the existence of Phlogiston, martian canals, Luminiferous Aether, the Steady State Theory, Cold Fusion, Hollow Earth Theory and Phrenology were all absolutely true, right?
Except that *none* of these were theoreies that made specific, testable predictions in as many different fields as QM and got all the predictions correct. Phlogiston was the only one that even came close, but it quickly became difficult to reconcile with observations. Quantum mechanics, on the other hand, is central to our understanding of phenomena as varied as subatomic particles, solid state theory, the emission of spectra, etc. To place it in proximity to these pseudo scientific ideas is both laughable and enough to show you understand bvery little of how science (as opposed to politics) is done. Creation 'science' belongs in your list, not quantum theory or general relativity.
