So, the Moon is not flat. You can see that the landing site is not on the center point of the Moon visible side. The curvate (yet again) cause the Earth to look so near to the Horizon. The picture is zoomed too.
I recall that I could not wrap my head around the globe earth/gravity stuff when it was taught to me as a child. I didn't understand how globe earth would be possible. Flat earth makes a lot more sense. -Well, the answer is obvious. You're a fucking moron
