Lol... I've just got normal eyes.

You seem to have a rather horrible misunderstanding of how gravity works, and how planes fly relative to airspeed, not ground speed.

I mean seriously

A river that flows 4000 miles against the supposed curvature of the earth

... are you trying to seem stupid or is your understanding of gravity really that far off?

One last thing. Flat-earthers are just the funniest bunch because WHY!? Why would anyone give a flying fuck about lying to you about the shape of the earth... It's a conspiracy theory that's literally bread from a joke.

I'm out.

Enjoy your angry confused life
