I have to give you credit, you've studied down this rabbit hole so far that you make convincing arguments. I just want to give up at this point and let you suffer the consequences of all that misdirection from the truth, but there are so many other fun phenomena that prove the world is a globe that I just can't seem to stop thinking about them...

Like how about the way Eratosthenes calculated the earth's size waaaay back in 240 BC by measuring how shadows fell at different latitudes? Why are shadow lengths different if we're on a FE?

Or how about the simple way nighttime works? My family in Bangkok often sees the sun rise as I see it set and wouldn't the easiest way to cast that huge shadow be us living on a globe?

Or network propagation times? We can all measure distances around the planet in milliseconds by using a simple ping command... And no one seems to notice any pings that take longer than pinging the far side of the globe from themselves.

One thing you were right about though, I don't have a firm grasp on your model of FE. I know some think it's a simple disc & there is a huge boundary wall in Antartica instead of a pole. Others think it goes on forever. Some believe space exists and others don't. Some think other planets are spheres and only we don't have one. What exactly is your chosen model?
