How can people believe the earth is flat Jesus Christ we are in 2017!!!!!!!!!!! Please evolve yourselves
People don't believe the Earth is flat, they know it is Flat.
You believe to stand upside down and sent data through Vacuum.
Outer Space does not exist the way it is propagated.
Don't matter how high you go the horizon will be at eye level.
Water will always seek the lowest point with least resistance.
not sure when was the last time you were in an airplane but im pretty sure i had to look downwards to see the horizon
