Why is football called football when you hardly use your feet

Although what Americans call "soccer" and the rest of the world calls "football" consists of almost all players using their feet to play the game, Americans decided to use the name ''football'' for another sport (What other countries call American Football). Some feel that this is incorrect and that the sport doesn't fit the name since probably 90-95% of the time the "football" doesn't touch any of the players feet. But it should be understood by all that there are no rules or laws of the world saying that a sport must be called by a name that the majority of the world uses, and it should also be understood that although the ball might not "touch" a players foot for most of the game, feet are being used for much of the game, including running, kicking, and scoring.
