Why argue over flat Earth? Why not just prove what people say are false? Leave FE out of the equation. Prove the curvature etc. Because we don't know, we can't prove. Use topics of discussion like gravity, distance etc to prove points. Show true pictures of the planets and how they cgi them up. Look for pictures of Australia see if everyone is upside down lol.

You prove the curvature by observing the curvature.
