I won't, because both observations have two possible answers (at least). First the earth is stationary and the stars rotating around it. Second the earth is rotating within the fixed star field. See the issue? That was why my first question was 'what is your fixed reference', which you gave a rational answer, 'there is not one', yet now you are claiming relative references as fixed.
