Do some research dude. The earth is not round. The equation to calculate curvature, 8”mile^2 does not hold up in real life. I have done the tests myself. If you care, go do them yourself.

Edit: basically, if something is 10 miles away from you, there should be 800” of earth inbetween you and the object completely blocking it from view unless it is over 800” tall. If you use a nice camera with a good zoom lens, you can see full objects much farther than 10 miles. Explain how that works on a globe earth?
