Astronomers are able to see distant planets rotating around their own suns, just like we do.

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.
You did not answer my point JQP, you brought up a strawman to the point and knocked it down. GPS satellites use VERY specific math and engineering. The exact same equations in math and engineering are used to get a satellite circling Jupiter (which is in motion, rotating) or in orbit around Earth (also in motion, rotating).

Seriously, this point needs to be addressed specifically. Geocentrists need to put up formula on how and why GPS works within a stationary earth framework and show that the calculations are IDENTICAL to those of a rotating Earth, otherwise, move this theory back to the junk bin where it belongs!

This is the crux of my argument and why Geocentrism does not make sense. We have applied physics, engineering and mathematics that one must ignore for the Geocentric model to work.

You cannot deny this. Math is math regardless of the motives behind the calculator.

Edit to add: for those unaware, GPS technology completely refutes the geocentric model because GPS positioning systems use math based on a rotating earth with specific stars chosen as the fixed point of reference! Not the stationary earth, but as it appears, the stationary stars. Using general relativity in calculating time, global positioning is achieved. None of this is possible under the Geo model, as JQP wrote earlier arguments against the accuracy of general relativity.

Without these specific details, which are the literal antithesis of geocentrism, GPS tech as known by humanity today, would not exist.
