on a spherical earth the horizon would appear as a straight line no matter how high up you go, because it curves away from you at the same angle in all directions. This means it would curve out of view at the same distance no matter which direction you look, which from your perspective would look straight and uniform.
Ironically if the earth was flat then a non-uniform horizon would be necessary and documented, because when you go near the edge, the shape of the horizon would take on the shape of the edge instead of having a uniform and consistent horizon everywhere on the planet.

I didn't say it appears flat... I said the horizon appears as a straight line...
It still would not appear flat because you could see it curving away from you in all directions...
What you're expecting to see, the horizon bending in an arc right to left, needs an egg shaped earth.
Tell me one other shape besides a sphere that appears identical no matter which location or angle its viewed from?
