There seems to be assumptions that we have satellites. Yet,  no real proof that all communication isn't groumd based. I think its foolish to try and prove flat earth using theories. There's no real science or evidence that supports satellite orbits.

Hey FLBoy, 

Welcome to Science!  Like you suggested, I was a "Round Earther" until about five years ago when I started looking into Flat Earth.  Ultimately, I had to draw my own conclusions on what the world looks like. 

In my view, it looks pretty flat from the surface, but as you go higher in the sky it looks rounder as seen from planes and satellites.  Why the earth doesn't look "flat" from space is a bit complicated, but I included a few pictures below to help explain:

In picture 1 (https://www.nasa.gov/feature/goddard/2017/goes-16-sends-first-images-to-earth) you see a satellite photo of earth . In picture 2, I tried to replicate this image by taking a flat earth map and putting a glass dome above it to represent the atmosphere and give it a spherical look.  Picture 3 illustrates what I think the earth looks like from far away at the time of this satellite photo.  I don't know if satellites are high enough to get this view or if the dark side of earth can be seen at all.  I suspect when people see earth from space, they assume darkness is caused by earth's curvature rather than the suns lighting effect.  Either way, everyone's shooting in the dark 



To get more fancy, here is another photo from space showing half the earth illuminated by the sun (https://www.met.ie/tracking-hurricane-lorenzo).  I posted my versions next to it.



And keep in mind the flat earth map I used needs to be edited in order to properly reflect all the land mass seen in the satellite images.

Here's a better view of the materials I used.  The map with a dome is on the left and without a dome on your right. 



Like you said, it may not be so obvious as to what the shape of the earth is from different perspectives.
