You ought to read a little bit into the history of astronomy, particularly planetary motion. If the ancient Greeks had applied Occam's razor then we would've abandoned geocentrism long before Copernicus.

We should've listened to (and built on) Aristarchus of Samos instead of Ptolemy's deferent/epicycle contraption. All of this because everyone wanted to hang on to Plato's assertion that the heavens obeyed the mathematical beauty of circular forms.
