Who looks DOWN from a mountaintop to see the horizon?

I did, Kitt Peak, sunset. The shadow of the mountain converged at infinity above the horizon. It was a spiritual experience.
I hope you are not presenting the flat earth argument that the curvature of the Earth is a parabola.
The equation for a parabola is incorrect for a sphere, y ≠ 8⋅x².

I CLEARLY posted 8" per mile² and you OBVIOUSLY know what that is...which is NOT the equation for a parabola and IS a common approximation used to describe the drop in height due to the Earth's (a globe with a fixed radius) curvature over a given distance.
