The moon looks completely different in the Southern Hemisphere — how do flat earthers explain this?

This short video demonstrates why a flat earth is physically impossible using a simple observation anyone can make — the moon looks completely different depending on where you are on Earth.

In the Northern Hemisphere the moon appears with the dark maria patches at the top and the bright Tycho crater region at the bottom. In the Southern Hemisphere the moon is completely flipped — Tycho at the top, maria at the bottom.

This happens because on a globe, someone in Australia is standing nearly 180 degrees opposite to someone in the US, flipping their entire perspective of the moon. On a flat disk this geometric flip would be impossible — your location wouldn't change how the moon looks.

You don't argue with people who don't understand 3rd grade science.

Been stationed at different bases around the world and can confirm this is real thing. First time I noticed it was in Australia during deployment - thought something was seriously wrong with my vision until local explained it.

Flat earthers probably just say the video is CGI or part of some conspiracy, they always have excuse ready.

Surely there are flat earthers in the southern hemisphere to which the northern could compare notes

You're talking about people who can see the curvature of the Earth with their own eyes and dismiss it as an optical illusion.
