TLDR Time zones, lunar eclipses, ship disappearances, shadow measurements, and flight paths are just a few of the reasons that provide evidence against a flat Earth and prove that the Earth is a sphere.

You can learn 10 reasons to prove that the Earth is a sphere on this episode of Everything Everywhere Daily.

Time zones provide proof that the Earth is a sphere because the sun rises and sets at different times based on latitude and longitude, which wouldn't happen if the Earth was flat.
03:44
The moon, lunar eclipses, and the visibility of constellations in different hemispheres provide evidence against a flat Earth.
05:30
Ships disappearing over the horizon and the presence of satellites provide evidence against a flat Earth.

By measuring the length of a shadow cast by a stick in Alexandria and comparing it to the direct sunlight in a well on the tropic of cancer, Aristocenes was able to calculate the circumference of the Earth and prove that it is a sphere, and it is also possible to see farther from higher heights, which wouldn't be possible if the Earth was flat.
08:58
At high altitudes, you can see the curvature of the Earth from an airplane window, and flight paths and the shape of other celestial bodies provide further evidence that the Earth is a sphere.

In a documentary about flat earth believers, a group of flat earthers funded an experiment using a laser gyroscope to detect the rotation of the earth, but when the gyroscope showed a 15 degree rotation every hour, they immediately dismissed the results.
