If we see the sun set due to prospective, why doesn't it get smaller? Because for everything else that goes away gets smaller, so why doesn't the sun? Or does the sun get smaller and we just don't notice it? If that's the case prove it gets smaller.
The sun is very very large and very very far away IMO.
A correct observation that doesn't help to explain the FE theory. If it's very very large and very very far away it would evenly illuminate the entire disc, which it doesn't. It would always be visible from all parts of the disc if it is daytime anywhere on the planet, which it isn't.
That and atmoplanic lensing.
Sounds like a made-up fudge factor.
I could equally claim that not only is the Earth not a sphere, and not flat, but is actually an inverted cylinder. So why can't we see Australia above our heads? Because "anti-aetheric-calamity-waves". These "anti-aetheric-calamity-waves" simply give the Earth the appearance of being flat or spherical, but the reality is, inverted cylinder.
See what I did there? I made something up to explain away observations that contradict my theory. That, in a nutshell, is the Flat Earth Theory.
