Fun fact: unlike linear motion, rotation is absolute. Accepting that the Earth does not rotate would require us to accept that distant galaxies circle it at tangential speeds many times greater than c. It can be logically consistent, but we would have to come up with an explanation for why the entire universe rotates around a particular object, and for why the speed of light has an exemption for this particular type of motion and none other.
