You believe that the earth moves in the absence of evidence for it. That's why GR was created the way it was. MM showed no movement as has every other experiment design to detect this supposed movement.
GR merely says that you can consider any point as being fixed (including the earth) because the motion of the earth through space could not be detected even though everyone believed it existed.
Once 'science' got used to assuming that undetectable entities exist, 'dark matter' and 'dark energy' followed to patch up other observed anomalies.
Apparently gravity is another theory you have fundamental problems with.
And what explains the stars retrograde motions? Epicycles? Epicycles within epicycles? Why do you think things would move in epicycles in the absence of evidence?
