This Flat Earth Deception post features a video called Simplest Irrefutable Flat Earth Proof.
During the first 2 1/2 minutes, he says that he is not a fool, that he has a degree in math, and that he has been practicing law for 30 years. And he’s not a fool, remember that as you watch his Simplest Irrefutable Flat Earth Proof. 😛
Of course what he ignores is that when the plane flies east on the flat earth model the pilot would have to constantly turn left, to maintain the curved east direction.
He acts like North is ‘up’ in space, but there is no direction of up and down in space; so the bottom of the globe is not down, and the top is not up.
The forces of the globe earth cause things to be pulled toward the center of the ball earth.
Honestly, if you think that his explanation is a valid proof, then there’s not much I can say to convince you otherwise.
