I guess you're reply got removed. I really would send you a thousand bucks but I know it's impossible to prove curvature. Even your example of Polaris is simply proving the Earth is not a globe. Instead you just simply don't understand that objects farther away from you. Lower on the horizon. It's basic law of optics. When you measure the angle to Polaris from two different points on Earth, And then you try to account for the curve. That's when you realize that Earth cannot be a globe. Otherwise you would have two polaris stars.
