I saw this youtube comment that sums it up beautifully:

Me: If the world is flat, why do ships disappear over the horizon hull first and sail last?
Flat Earther: Perspective.
Me: Okay. If the moon is small and close, why do people north of it and south of it see the same side and the same phase?
Flat Earther: Perspective.
Me: Interesting. If the sun is always circling over the flat Earth, why does it sink below the horizon at night?
Flat Earther: Perspective.
Me: Got it. If the stars are all on a disk rotating around Polaris, why do people south of the equator see them rotate around a southern celestial pole?
Flat Earther: Perspective. By the way, if Earth were really a sphere with no dome over it, what would stop the air from escaping out into space?
Me: Gravity.
Flat Earther: Oh brother. You Globe-heads think gravity is the magic answer to everything!
