I've posted three questions so far, and I haven't gotten a sensible answer to any of them. The discussion of each of them has devolved into nonsense and insults.
If I didn't know better, I'd say that some of the people on these boards are not taking this subject seriously! Let us proceed with civility, and let us reason together:
I live near a large American airport. Often I will see planes take off and fly away. The plane appears big when it takes off, and then it gets smaller and smaller, until it's the size of a dot, and then I inevitably lose track of it as it flies below the horizon or behind a building.
From what I can tell, this is the Flat Earth explanation for sunsets. The Sun gets further and further away, until you can no longer see it. But if that is the case, then why does the disk of the Sun not appear smaller as this happens? The Sun appears to be roughly the same diameter at sunset that it does during noontime. One explanation I have seen proffered on these boards is that the Sun's size is magnified due to some sort of atmospheric lensing, but this seems impossible; a flat Earth implies a flat atmosphere, and as anyone who's ever worn glasses or used a magnifying glass can attest, lenses only work if they are curved. And in any case, why would this not happen for airplanes also?
The FAQ makes no mention of this conundrum, and this is an unfortunate oversight. (Surely I am not the first person to ask about this!)
