You do know anyone can write anything in wikipedia.
Basketball is easy, it was a new idea that came recently from one person. It was borne with the rules and they have not changed much since then.
Football is extremely hard, especially when we look at the world. If we limit ourselves to the UK. back in the day many played a game with a ball that involved some holding and running and some kicking. In the UK at the time all Universities played with different rules, eventually a bunch of them thought it would be fun to have inter University games and so decided to create uniform rules. That sport was called association foot ball, in Rugby they decided not to join and make their own rules (much more ball holding) and that became known as rugby football. Eventually in the UK Rugby foot ball became just Rugby and association football became known as soccer or football. What does this have to do with NA football that is neither of these. It got born at the same time kind of the same way. That same football with regional rules in the UK was being played in all ex British colonies. It eventually became Soccer, Rugby Canadian football and American football. Who invented Football (what we call Football) makes no sense, because no one can say who and when they played football and when it became Football.
