My favorite is that in the same vein, Aristarchus estimated the size of the sun to be much larger than the earth (although he still severely underestimated it because it’s so hard to measure), and therefore proposed that the earth should orbit around the sun. And the main problem with his theory was not any religious objection, but rather that his model would imply that there should be parallax visible among the stars. Unless they are, you know, ridiculously far away.
