Bro, there is nothing you could say to these people. Humanity developed technologically because of basic scientific principles, and these off-brand diva cups argue the most basic conclusions that allow them to post on the internet from their wireless computers in a centrally air conditionedhomebasement. Then, when a frustrated poster presents actual facts they have this nonchalant "you never know" response. Yes we do know because primitive concepts like a round earth gave way to every advancement since before the dark ages. Even in the dark ages the majority of scientists didn't bother with this shyt.
My pops said there's always three generations: one builds, the second defends, and the third forget. Generally he's a piece of shyt, but I can see it in America. The first generation were the (deeply flawed) founders. America's second generation was WWII and the Civil Rights movement, and now we're here where none of that history matters because individuals created their own. I could be completely off base here, but there is some universal fukkery about to go down.
Edit: The third generation forgets.
You're right about one thing, this era of humanity has completely forgotten the ways of more adcanced ancient civilizations, which is why the ancients were flat earthers with strong command of natural forces while current society is just barely rediscovering some of the surface-level enlightenment of ancient societies while also polluting this plane in the process
But I will literally debate/educate you on any and every flat earth principle that you think you understand
In this thread or any other one.
