You cannot get a shot of the Earth from there without long exposure shots. Even blue marble photo is a fake. Apple used an updated photo of the Earth and he admitted it was faked. He had to photoshop in clouds and terrain and other shit.
The Earth is a globe, though. Simple observation is during an eclipse, the shadow will reveal the curvature of the planet. Another is radio signals. We bounce the signal off the ionosphere to counter the curvature. If it was flat, you would simply build a taller tower and service everyone.
