There are many
"proofs" that both prove, and disprove a flat Earth, and vice versa for a round Earth. This, however, may be the most reliable piece of proof that proves the Earth, is in fact, round, and not flat.
Satellites are a big piece of human society, without them we wouldn't have basic things like location tracking, GPS, maps, etc. Without satellites, we'd not be where we are today with all these modern capabilities. There are quite a few reasons why satellites disprove a flat Earth model, but the most important one is this: satellites move in a straight line across the sky, and then disappear beyond the horizon, because they're orbiting a
round Earth. If they were
"orbiting" a flat Earth in the fashion that the Sun and Moon would, they'd never dip below the Horizon.
Now, before you attempt to provide a
"rebuttal", I've prepared a few responses of my own to common ones you may post.
Satellites could simply be orbiting around a flat Earth OP, like an orbit described with a round Earth model.
No. If gravity behaved like this, then the Earth would've formed into a spherical-ish shape, the way it has. You may argue that it's held in by some
"magical force", but at that point, you're just making frivolous claims with no proof whatsover to try and prove the existence of a flat Earth.
But OP, satellites are just lights or computer generated visuals projected onto the sky by the most "evil" organization of all, NASA.
No. There are a few problems with saying this here. First off, in order to project a light into the sky, we need to have a surface to project it on. We can't simply project it onto a cloud, because the light would distort along with the shape of the cloud. Secondly, if this
was happening, then we'd see light beams being projected into the sky from the ground somewhere, and I've yet to see any news about one of these things being discovered. Secondly, you can't just
"project" a computer generated image onto the sky because again, we run into the same problem. You need a surface to project it onto, and we'd also be able to clearly find where it's being projected from.
OP, OP! These are clearly just a bunch meteors, comets, etc.!
No. These aren't meteors, or comets, or the likes. These bodies
do not move in a straight, predictable pattern. The often flash across the sky before burning up in Earth's atmosphere, or are too far away and not visible. The reason these items are visible when they're far away is because, unlike satellites, are not composed primarily of highly reflective material.
You stupid round-Earther OP! Satellites are imaginary creations that satanists want us to believe exist!
If they don't exist, then what are the nice bright, slowly-moving dots you can clearly see in the sky on a clear, dark night? They certainly aren't meteors, or light projections.
