Who knows.Why do that flat earth people even exist in this day and age?
I’m still trying to figure out how they see the bridge across Lake Ponchartrain in Louisianna!
In the middle of the drive across the bridge, for 8 miles in every direction, you see nothing but water. The land behind you disappears below the horizon. Eventually you see the tall buildings of New Orleans magically rise up from the water because they are over the horizon.

The world is round. You can prove it to yourself without help from anyone else, just by going for that drive in your car.
