How about the North Pole?
If the sun goes in a circular orbit (around something) approximately above the equator, that would mean that an observer at the North Pole would either see the sun travel in a complete circle at the same elevation (about 20°) or not see it at all because "the light isn't bright enough to see that far away".
The only way the sun could rise or set at the north pole is if it's orbit shifted north and south on the same day. Ignoring the obvious problem of how, that north/south shift is how seasons are supposed to work sooo...how do seasons work?
I always argued using the model of the sun rising over the circumference of the earth because even though that's obviously stupid, it's much less stupid than the idea that the sun spins in a constantly changing orbit directly above us and we don't see it at night because it's too small.
Acktchewally, if you knew anything about FE, you would know that the sun orbits in a different bullshit model where your specific scenario works correctly.
