      The surface of the earth is so huge for people. And all the creatures on this planets are effected by gravitational force from the earth. It is so difficult to get rid of the gravitation that there is no chance to fall off.

      It’s a ball shape, there is no edge.

      Gravity keeps you stuck to the ground, and there is no edge to fall off – it’s a sphere.
