The idea that you can see something from the ground, regardless of its distance, does not prove in any way that it is in some kind of orbit around a globe.
Well what about how when a satellite dips below the horizon, then rises from the opposite. On a globe that would work, but not on a flat plane.
Planes can dip below the horizon and end up on the opposite side. They're not in orbit, so why is a satellite?
You know, we can see satellites orbiting from the ground... They clearly aren't faked. You don't even have to be on the ISS to see them. We can also see the ISS from the ground.
I can also see airplanes from the ground, are you about to tell me airplanes prove the world is round because they're in orbit?
No, because airplanes don't travel at orbital speeds, they don't follow Kepler's laws, and they don't stay in the air indefinitely. That said, airplanes CAN prove the world is round using flight times.
Flight times provided by "trustworthy internet sources" I'm sure.
Also, plans would follow Kepler's laws, if they existed, since Kepler's laws would govern the orbit of the Earth, which would govern airplanes. If they magically don't follow Kepler's laws, then perhaps you should explain why.
