>Satellites can exist but not by orbiting a gravitational field around a spherical earth, but rather circulating above the flat plane.

But their angle above the horizon from different viewing locations can't work on a flat plane. The viewing directions don't intersect at a mutual point on a flat plane but they do on a sphere. The same goes for the Sun and Moon.

I plotted Iridium 62's angle above the horizon from 30° north latitude to 50° north latitude and the lines only intersect if the ground is curved.
Here are the angles taken from Stellarium. The first one is from 30° north latitude.
