The argument for flat earth is you can't see the curve..... well no shit the earth is fucking massive. You would have to be far as fuck from the earth to notice a curve. I can see the curve at the ocean watching ships come in. You see the top of the ship and slowly the rest as it comes closer from far away. That is the curve. People expect to see curves like 3 blocks away LOL.

thats called atmospheric density ! things get smaller and smaller the further they are away ! binoculars can alow u to see that ship that disspeared over a (supposed curve )in all its glory and then telescopes are even better
