>how can i see so far it doesnt make sense
it does. especially over a body of water since the water cools that layer of air making it more optically dense for refraction.

but you know its round dont you shill

you might as well educate yourself. what i mean is simply that instead of the light going over your head and off into space, it is cause to curve downwards a little bit over a long distance so it hits your eyes.

ok. how do you know where you are on the earth? how do you measure how far you have gone?
theres really no need to be an asshole about this anon. im merely asking you to carefully explain how you think 'go sail a boat' is supposed to interact with what flat earthers believe.
are you pointing to the fact that distances south of the equator are messed up on the usual flat earth maps? if so, you can just drive across places south of the equator since the land masses should also be much bigger on a flat earth map than they actually are.

If you're talking about how you can just sail east and wind up back where you started (more or less) then that wouuld be the case on their flerf maps too.
