What does fixed at the centre mean. What does revolving around us mean?
I'm not trying to annoy you, I just don't think it's that obvious...
It means a frame of reference pinned to the center of the earth behaves as an inertial frame of reference. Prior to relativity it was obvious economic and accurate description of behavior of solar system is difficult to reconcile with this. Relativity says there is no such thing as inertial reference, period.
