Here's the part i love about flat-earth logic. They use two theories that are mutually exclusive:
FACT: You cannot see the edge of the earth or even another continent, mountain on another continent, ship sailing out to sea, or whatever.
FACT: Clouds appear to 'touch' the horizon.
Ok here we go.
Apparently, we can't see things getting farther away because air eventually becomes opaque the farther out it gets.
Apparently, the clouds appear to touch the horizon because of perspective; everything gets pulled closer together, so while they never actually 'touch', they appear to do so.
So the air itself blocks us from seeing those distant things. Ok, good point. We've all been in a fog, so that's not hard to imagine. And we're all familiar with perception, so that's not hard to imagine either. But answer me this: If the air is so opaque that we can't see a ship or mountain or anything, how is it that we can see the clouds that MUST be farther than that ship sailing off into the horizon (since they are, in fact, behind the mast) when said ship disappears from view?
