Canadian (not just CFL) football was not 'invented.' It developed over many years, just like American football did. Countless numbers of people were involved in the development of both the Canadian and American games.
In Canadian football, a team has only three downs to make a first down. That's why Canadian football is a "wide open" game, unlike the more static game that's played in the US.
Four downs would make it too easy to get a first down. As it is, Canadian Football is a much more wide open and high-offence game than its American cousin. The down rules in the two games were settled a long time ago and the other rules have been tweaked to make the game more balanced--to help the defence in the American game and to help the offence in the Canadian.

It depends on what you mean by soccer vs football. If you are referring to the beautiful game. Most countries and territories call it football or something similar to the name. However, some countries say soccer(Association Football) because they have other sports or versions of football, such as American Football, Canadian Football, Australian Football, Gaelic Football and Rugby Football.
