Flat Earthers, please tell me, is the horizon I see so clearly actually real?
If the horizon is an optical illusion caused by the non-transparent atmosphere, why does it behave just as if the round world is dropping away?
Why can microwave radio signals only reach the visible horizon? Why can someone beyond the visible horizon receive such a signal if they raise their antenna on a mast to a height that is in line with the radio beam in the Round Earth model, but well above the beam in the Flat Earth model?
Why can I not see Mt Everest? It sticks well above the thickness of the atmosphere.
