Flat earthers are dumb as bricks. Take a little bit of time, buy a weather balloon and send up a go pro to the upper atmosphere. You can see the damn earth is a sphere.
If you cannot believe this, then well shame on you.
How does the sunset work? How does the sunrise work? How do seasons work? What about the GD moon and its shadow, the earths shadow looking back from the moon? I mean shit. The world is damn pretty much spherical in shape. There is no question.
