It really should be just that simple.

I was checking out this awesome bathymetric map of the Earth and started wondering; forgive me. Carl Sagan and Bill Nye have me pouring over reductio ad absurdum (argument to absurdity), also known as Aristotle's "reduction to the impossible". This form of logic is useful for attacking seemingly complex theories with reduction to obviously silly assumptions that disprove the conjecture.
If Flat Earthers were correct, then there is another side to this map. Instead of traveling straight from eastern Russian into Alaska (which we know happens because there are Russian bombers doing flybys today), there should be a whole set of other continents and waters on the flip side of "Flat Earth". Even if there's no water there and it's entirely barren rock, their theory would imply that we've only mapped half the Earth.
But, that's absurd given how this bathmetry is distorted in order to fit the spheroidal Earth on a flat, 2D surface. By simply building a 2D model of the Earth...we literally eliminate any possibility of any additional unmapped surface. It's easier to reverse this process and take the 2D map and project it onto a 3D sphere of the hypothetical Earth (geoid).
Carl Sagan did have quite a lot to say about argument to absurdity (which can be used to disprove both Flat Earthers as well as prove the Inverse Square Law). Arguing to absurdity (like Bill Nye also advised) is a pretty effective way to pounce on Flat Earthers ("find an edge!". It may not help convince THEM, because I think they tend to be the type of people are either mentally incapable, or willfully resistant to scientific inquiry. They just jump to "it's fake". But it helps make the ridiculousness stand out like the hot mess it is.
There comes in again the whole "Fake Moon Landing" phenomenon....by dismissing the Greek geometry and German astrophysics that ultimately led to the whole space race...even crazier things like fake Moon landings and space debris = Aliens become imaginable. Imagination is incredibly important to science, it also has its checks and balances in the methods. That's why we gather data for experimentation based on hypothesis, to build stronger theoretical frameworks. Humans could NEVER have left the Earth and started exploring space IF we continued to believe it was flat. Today we have millions of pictures and maps of the spheroid Earth ONLY because we correctly induced its true size and movement centuries ago, first with math, then with experimental data, and finally laws that accurately predicted things.
