Because I have no idea what sort of evidence you want. You ask about a ice wall, I point you in the direction of Jarle Andhoy, and you dismiss it. That is how it is, no matter what evidence I would provided you would dismiss it, for one reason or another. Last time around, someone claimed there was no curvature for the first 15 miles of water and we still on a globe, like what do you want me to do about that, I know there is no curvature for the first 15 miles, nor the next 15 miles, or no matter how far you look. Get a something with a high zoom and you can see Chicago across the Great lakes 50 miles away on clear days, on standard globe math there should be over 400 meters of curvature, and the Chicago skyline is not that tall. Start recording the sun position on the sky at same time every day and you get the solar Analemma, then you can understand how the sun moves across the sky throughout the year, guess what, it spends more time in the northern hemisphere, then in the southern, that does not work on a globe, but is how we expect the sun to move on a flat earth, as the North is the centre. On the equator the sun always turns right, just like a clock would, no matter where you are, the sun always has a right turn to it. I can start posting more evidence though, for you, next thread Tuesday I think.
