Morning Scepticism: Interpretation

Geocentricism looks plausible because things seem to rotate around the earth. The sun, moon and stars rise in the east and set in the west. Yet geocentricism has long been abandoned, and the Sun is at the centre of the solar system. One could object that it looks like the earth is at the centre, yet that is exactly what the heliocentric model predicts as well. There's no hidden trick, just a different model can explain the same appearance.
