We actually don't know if it's called football because it's a game you play by kicking a ball with your feet, or whether it's because football games are played "on foot" rather than mounted on a horse.

Association Football is actually the odd one out in not letting the outfield players handle the ball like basically every other code of football. Though in its formant days you could, and there was stuff like rouges "marks" in Aussie Rules were a player could catch a ball with raised hand and then take a Free Kick.

It's all fascinating, and how they all were codified around similar times too.

The part that's always interested me is how we've probably being playing football games since like the 1300s (and kicking a ball way beyond that) but basically none of it survives on the historical record past a few Medieval Shrovetide and such type games still played today, but no records of teams or local tournaments or such. There might have been a 1500s Ronaldo who played foot-ball town to town scoring goals and we just don't know about it.
