IF YOU SAY THE EARTH IS NOT FLAT, YOU MUST ALSO THINK YOU CAN WALK THROUGH WALLS, GENIUS

Things orders of magnitude larger or smaller than us literally exist in a different and inaccessible dimension. We can no more consider the Earth "round" than we can consider ourselves as able to pass through walls since it is all just a bunch of floating mini-particles at a small enough scale.

People who truly consider the Earth round would roll not walk. They would have no use for an electric motor, except uphill, preferring to just coast along with the curve of the Earth. But since it is clear the Earth is largely flat, bar some hilly areas, nobody does this just as nobody walks through walls.

If the Earth is not flat, you had better pull your money out of the bank because a robber could just walk through the vault gate and take it!

I have always considered that, since the Earth is flat from my perspective, it would always be ridiculous to call it round and directly oppose my lived experience. The flat Earth debate is a great segue into thinking about how reality is just a perspective. I'm sure amoeba have a very different perspective, meaning they live in an entirely different reality. Most likely stars are also living beings of some form, to such a star-being's perspective the Earth may indeed be round. But not to mine or yours.
