How can I debunk the arguments used by Flat Earth advocates?
Well, one of the arguments they use is the claim that the horizon always appears flat, so the Earth must be flat.
Ah yes, that's a common one. One way to debunk this is to point out that the human eye can only see so far. As a result, the horizon may appear flat, but that's only because we can't see the curvature of the Earth.
