Part 2/10:
Flat Earthers argue that the Earth’s diameter is approximately 23,000 miles, based on measurements from the North to the South Pole (about 11,800 miles). If the Sun and Moon were truly hundreds of thousands of miles away—as mainstream astronomy states—they would be visible overhead at all times. However, this is not observed; the Sun and Moon appear to rise and set, implying they are much closer than the distances proposed by conventional science.
