It really doesn't matter if it's flat or spherical. It doesn't change our current situation. Props to the flat earthers who kept trying but were bad at math.

Until we can escape from Earth and start colonies it really doesn't matter.

Until we have the tools to finally prove macro evolution, it really doesn't matter. Micro true by the looks of it, but macro is a whole other dinosaur so to speak.

Big bang is another one. All of this scientism bullshit that people preach doesn't provide the inquisitive mind with enough answers, it only leaves further questions.

And once that inquisitive mind gets going, it gets shut down by people who don't know better.

So if a child came to you and asked you how do you know the earth is round? You're just gonna say:

"It's math kid, better you know that"
