I love to play football 
It is a sport that involves kicking a ball with your feet in order to score goals.
It is called soccer or association football
It depends where. American football is called gridiron, and there is also rugby.
That is true
They used to be seen as peasant games in the past.
When was it initiated?
It's hard to tell, but I think it was initiated in Britain some time ago and moved out of Europe ages ago
Ok
Gaelic football started getting popular the end of the nineteenth century, but it also maintained their heritage in addition to following traditional rules.
