      This is a really good question.

      When all the bits of matter that would eventually make up the world started to come together this created a gravitational force (basically, any large body of mass attracts things to it, and this is gravity). Because gravity was pulling equally in all directions the matter became arranged so that it is a sphere (well, nearly a sphere).

      There was another very similar question asked earlier on in the week so you can find a bit more detail here: /niobiumj12-zone/2012/06/22/why-are-all-planets-spherical-why-are-they-not-any-other-shapes/

      Does my explanation make sense?
