It's all about mass mind control!
Why does flat earth matter? Because it hides the Creator. That's correct but if you look at it from a different perspective it's all about mass mind control! It's the ability to change your way of thinking and perception of reality. It's very powerfull! It brainwashes people minds. The heliocentric cosmology is the mother of all lies because it is a big lie from where other big lies depent: big bang, evolution and aliens. Without it these other lies dissapear inmediately. If they can make you believe that the earth is moving despites of feeling nothing is moving, they have succeded controlling your mind. Samething happens when you believe that people on the "southern hemisphere" is upside down. It's and absurdity but you believe it because we all have been brainwashed since we were born.
