Also the moon's size is the same is the same for all viewers, so it must be a very great distance away!
Please read the Wiki on the size of the sun and moon.

Please show some evidence that air can
magnify anything something like FOUR TIMES.
And, no unless you are still stuck centuries back, the refractive index of air is around 1.000293! It does vary with wavelength, but not over 1.000305. Kight might be bent up to 0.5° or so, but that's all!
Sometimes I think that the only thing "Zetetic" about Flat Earth beliefs is "The earth looks flat",
then everything else is guessed or bent to try to explain away the differences.This differs from the scientific method, which did start off with exactly the same conclusion, because "The earth looks flat" - it does and it was assumed to be stationary.
But, then more observations were made and some of those did not fit with the "Flat Earth" hypothesis - well you know the rest!
It's not much point preaching to the converted, or to the unconvertable.
BTW The nearest refence in the Wiki seems to be under "Constant Speed of the Sun", where all it talks about is a completely erroneous description of perspective - unless you go back to bendy light.
Still if you want to close you society to any chance of acceptance in the "more scientific" community, just stick to these ideas that go completely against all the discoveries on light propagation and so many other well accept "theories".
