There are different types or meanings of football, America is the only place that has the meaning of throwing a ball and trying to get it into an end zone. Other places it means soccer, and it can also mean rugby, but American football is probably the most common meaning for it.
American football has its origins in a soccer-like game that developed in the middle of the nineteenth century. McGill University of Canada helped to change American football to a game more similar to rugby. Walter Camp helped to standardize the rules of American football and make it more like the game we know today. Football is a competitive sport; it was first invented or established around 1873. The point of football is to catch the ball, which is kind of shaped like an egg, and try to run it across the other goal line, while you are running it the other team is trying to tackle you.
Football has been around for a long time it has gone from soccer, to rugby, and to what it is now as American football. Although it has been through all of those names all of them are still played all around the world (who invented american football).
