Oh...you seems to come here to prove something....But all of us(who joined)know the basis of the world(just like you). We don’t need any way to solve any problems. “Flat earth”just like a religion(I think) ,we came here to doubt NASA, we came here to doubt modern science, we came here to doubt the whole world!
We are not idiots!

I am chinese（live in south Korea）. English is not very well，sorry.
