Just a little extra:

Just putting that out there, the world isn`t flat. I can prove this because let’s say you’re in the ocean. You start at land and you make your way to the middle of the ocean. When you look back you can’t see land anymore because your curling around the world. Its kind of like an ant walking over a baseball. You put a baseball on the grass or wherever and you lay down and all you have to do is stare at it. Eventually an ant will climb over it. You can see the ant on half, and then it just disappears, its just like the planet.
