Wen you go behind the horizon, the horizon blokes the sight if the observin person.
It's true,
I do not thing that you can reply this.
Charlie!! Haven't you figured out that these Flat Earth guys are just joking around? They really do not believe the Earth is flat! It's just a big joke! They are having fun trying to see how many people will fall for their joke! They know the Earth is round, they are just having fun with you, trying to get to you! They know only a complete, uneducated moron could possibly believe the earth was flat! They know it is a sphere! They wouldn't really make total fools of themselves thinking the world is flat! They know that in fact the Earth is round! I really am enjoying their joke, it's funny to see how many people have fallen for it! It would take a totally retarded, uneducated, blind crack head to think the world is flat! Can you imagine actually meeting someone so stupid that they actually believed the world was flat? I would laugh my ass off for weeks if I ever met someone who thought the world is flat, I dont think I would even be able to stand up I would be laughing so hard!!
Anyway, dont take it seriously, they REALLY DONT believe the Earth is flat. Remember, it's just a joke they are playing!
Flat Earth, HaHaHaHaHaHahHaHaHaHaHaha!!!!!!!!!!!!!! That is HILARIOUS!!!!!!!!!
