Seeing as I have had no explanations of how satellites work, GPS, your cellphone, datelines, the fact that you can't see all the continents from space at the same time I basically conclude that flat earthers are ALL just trolls. Go f**k yourselves!
The earth is... a collection of atoms separated by space, just like you are. These exert forces to keep them together. The larger the mass, the larger the force which creates gravity. Smoke enough dope and you'll see the space between the atoms and realize where you are in the grander scale of things.
