ELI5:Why is it called (American) football when you mostly don't play it with your feet?
gpt
It's a historical term dating back to the very earliest days of the sport, when it was a hybrid of rugby and what Americans call soccer. Later (but still before the introduction of the forward pass), the game evolved to one where touchdowns were worth four points and what was the equivalent of field goals, five. This placed a higher emphasis on the kicking game than the modern game. 

The sports associations at the time surrounding football were mostly collegiate and they had "football" in the title from those early days. The name has stuck even as the game has evolved to its modern form.
