Many ancients knew that the earth is a spheroid because the water of Noah’s Flood didn’t somehow fall off the earth, logic 101, today’s flat-earthers illogical (for a variety of other reasons too), and we know that darwinism is bogus, a very weak hypothesis, because about 80% of the kinds (syngameons) of animals in the fossil record are with us today; flat earth and darwinism equally ridiculous.
