Ptolemy was not "wrong". His model worked quite well within the margin of his measuring tools.

And, in fact, Ptolemy was more "right" than heliocentric circles (as opposed to ellipses).

You have to have both elliptical orbits and inverse square law forces to predict better than Ptolemy.

It wasn't until the telescope allowed seeing Venusian phases that geocentricity was actively disproven.
