I was a good footballer while growing up, football is a sports thats involves kicking a ball with a foot, controlling passes and scorng a goal. 
I know about football. It is called soccer in the US
yes it is, over 24.4 million people participate in soccer in the US
Where was the origin of football?
i think it started in Greece but Contemporary codes of football can be traced back to the codification of these games at English public schools in the 19th Century\
But i learnt it was created by the English people
Am not really certain about it but American football resulted from several major divergences from association football and rugby football
I am glad to know all this. How many countries participate in football
It is played in all the continents of the world but Sports commonly called "football" in certain places include: association football (known as soccer in some countries); gridiron football (specifically American football or Canadian football); Australian rules football
