Which is the best sport in the world and why?

Clearly football (soccer). No one cares about American football or the super bowl outside of the USA, although it is growing in popularity.

Football is played in every country and has massive coverage for EPL, La Liga and Serie A etc.

Football is popular because only a ball is needed to play. It is a game of skill, where ball control is far more important than physical conditioning. People of all body types and heights can play soccer.
