I find it hard to believe that there are still people thinking that the Earth is flat.
But this debate will be over in the coming decades, when space tourism become a real industry and people will finally be able to see with their own eyes that the Earth is indeed, not flat.
Great explanation!
Cheers!
I think some of them do not really take it serious, but a surprising number of them do. It's weird to see that. I believe when we go visiting the Mars like a holiday to some choice country, the flat conspiracy will then die a natural death.
