Sun Altitude Dilemma

(Reposting because original post got deleted when I tried to edit)

Modern Flat Earthers generally hold that the Sun is always above the Earth’s surface, as it is impossible to deny it is always day somewhere. However this causes a dilemma.

Suppose the Sun’s altitude is less than 1000km. Then, when directly overhead, it will look at least 10x bigger than when over a point 10,000 km away.

Or, suppose it’s more than 1000km up. Then, even when 20,000km away, it will be more than 2.8 degrees above the horizon (it’s angular size is around half a degree), so for a good chunk of the world at least, it will always be well above the horizon, so won’t set. Ditto the Moon.

The first problem gets worse with a lower Sun, the second worse with a higher Sun. Some even claim the Sun is below the clouds based on their interpretations of some videos, so the 1st problem gets really extreme. Either way, the model predicts a clear observation that isn’t what’s seen.
