Original Note:

There are visual proofs of the earth being round, anyone can experiment by looking at a lighthouse at different distances or staring at a boat until it disappeares at the horizon. Eratosthenes used such optical proofs to measure the earth's circumference https://en.m.wikipedia.org/wiki/Eratosthenes
