Here is some food for thought;

If you have a straight line segment, and were to observe it from the perspective of looking at either end's point, that same line segment would appear to be a 1-d point.

If you have a 2D triangle, and were to observe it from a perspective looking at any of its sides it would appear to be a line segment.

If you have a 3 sided pyramid (most basic 3D polytope), and you observe it from the right perspective on any one of its sides, it would appear to be a 2D Triangle (most basic 2D polytope).

If you observer a 4D hyper-cube from a certain perspective it would appear to be a cube.

And so on, how we understand dimensions are completely reliant on our perspective, our point of view. Change it even slightly and the what's being observed changes too.

I have a question - why is your understanding of what the horizon is based on a 2d side view of earth when in reality - your view of the horizon is always in optical 3d perspective?

because multiple 2D side views can be put together from different angles to show a 3D object...

super easy drafting and design skills

sorry that's not an answer, your understanding of the horizon is clearly based in 2d, kinda odd dont ya think, please explain your reasoning.
