I don't recall Alpha answering to this. A lot is made of the horizon, especially out at sea. But the fact of the matter is that large ships disappear from view anywhere between 10-15 miles from shore, given that you're standing at sea level. Considering we can see up to 20 or so miles on a clear day, what would explain ships disappearing from view? I've read all about bending light and optical illusions, but in reality there is no real explanation for why would a ship disappear from view after sailing a certain distance from shore. If you're gonna scoff at bending water on a globe, then at least offer a plausible and credible explanation for ships disappearing over the horizon. On a flat earth, we'd see the ship until visibility prevented us from seeing further.
