In their own gif they need to make the light the sun puts out oblong which makes no fucking sense and there's no explanation as to why you can't always see the moon.
It's so stupid it's embarrassing to even debunk them.
Gravity bends light. Therefore, there is a tiny black hole between earth and the sun. You see, the black hole redirects the sunlight juuuuuuust perfect to simulate that sphere nonsense you sheeples believe in.
It's definetly dark on the other side of our flat earth.
And to prove I'm right: dark side of the moon by pink Floyd. The moon is also flat. Someone is flipping all those discs (you prefer 'planets') over every 24 hours, just like flat pancakes. How can you ignore all those obvious signs.
My favorite bit about Flat Earthers is that most of the ones who consider the question of other planets / moons believe that they are all spheres. Because they can see them. But the Earth is somehow a special case.
