>Flat Earth is trivially falsifiable. It's falsifiable, but not trivially. For example, due to atmospheric refraction we can see some distance around the curvature of the Earth. A common Flat Earth "demonstration" / "gotcha" is to show examples of photographs taken of distant objects, that shouldn't be visible because they'd be below the horizon (checkmate, Globalists). The optics phenomena are complicated, and most people have to take it on faith that the physicists aren't lying. And if you already think there's a global conspiracy to deny the Flat Earth, that's a non-starter. There are a lot of things like this where it's actually a bit more complicated -- some second-order effect that isn't satisfactorily explainable with high school physics. And they have them all memorized as talking points. So a naive debater can get caught unawares and look foolish.
