Retrograde motion cannot really be explained with a geocentric model. It was attempted and even believed, but the theories were far-fetched. (Easy to say with hindsight! :o)
I'm lucky enough to live in a rural setting (15 miles to the nearest town, and it's not very big or bright), so I get

There is no proof that can be observed with the naked eye that the earth is not the center of the universe. The motions of the sun moon and planets, including the equation of time, tides, eclipses etc., are all adequately described by the geocentric model. We do not need to accept the revolutiona
