I'm gonna update the list
ROUND EARTH-There is absolutely no compelling explanation for ships and buildings appearing to "sink" below the horizon
-Sunsets wouldn't work on a flat Earth
-The southern circumpolar stars can be seen from everywhere in the southern hemisphere when looking southwards, which would be impossible on a flat earth
-Foucault pendulum
-Cavendish experiment
-Coriolis effect
-Round Earth shadow in lunar eclipses (flat earthers try to pretend that it's some sort of "shadow object" or something
-Time zones make no sense in the flat Earth map and would never work with a spotlight sun
-Flight distances in the southern hemisphere would be ridiculous compared to what we observe
-The very fact that distances on globes are accurate disproves a flat earth, because geometry on a spherical surface doesn't work on a flat surface
-Photographic evidence (that, of course, flat earthers reject)
-Antarctica midnight sun
-Satellites and the ISS can easily be observed from the earth
-Satellites can easily observe the Earth
-Gravity variation between North Pole and Equator
-No Ice Wall in Antartica
-Rocket launches can easily be observed
-We are able to bring back rocks from the Moon
-We are able to place reflectors on the Moon, and shoot lasers on them
FLAT EARTH-NASA is a conspiracy
-???
