Part 4/13:
One common Flat Earth argument is that the reason we don't see the ice wall or the edge of the Earth is because our vision is limited. The presenter addresses this claim, noting that even if human eyesight had a maximum distance—say, 10 miles—it would still produce a circular horizon if viewed from a balloon or an elevated position. The logic follows that a limited visual range would still generate a curved, circular horizon because the line of sight would extend equally in all directions, naturally forming a curve consistent with Earth's curvature.
