My favorites are The ones who think that the Earth is kind has kind of a rim around the edge and the moon rolls across that like a ball lol
But I’ve seen plenty of them that are perfectly fine believing that all of the other planets are spheres.
It doesn’t really matter, I always just tell them to lower a GoPro over the edge and let us know what they find down there. I mean if there’s an edge there’s got to be something under it right? Well they better get going, that award-winning documentary isn’t going to make itself.
