You must be ten years old to ref the lowest division which is U-8. AYSO requires that you be at least 2 years older than the people you are reffing.
It is subjective to determine the greatest soccer player in AYSO as it is a recreational youth organization. AYSO focuses on participation, sportsmanship, and skill development rather than the determination of the greatest player.
There is no age limit to becoming a referee.
It usually depends on the soccer league you are reffing for, but most of the time you have to be in high school. The age limit is 10. this is to referee a u-8 game. Also you must pass the certification exam. Well, in my town you can be 10 to referee a soccer game. I am 10 and I can referee in Wisconsin.
You would be issued a blue card 2 min for to many men and maybe an unsportsmanlike conduct. Blue cards are shown in the Indoor soccer leagues. If this is a match at the professional level (MLS, EUFA, English Premier, etc), most likely the substitute would be shown the yellow card for entering the field without the referee's permission. The college level referee would most likely have the same response. In the high school leagues, there tends to be a little more leniency. Perhaps a verbal warning would suffice. In the AYSO level of play, there is even more leniency. I referee with AYSO, club soccer, high school and indoor. But remember, it is the discretion of the referee at the time the substitute enters the field as to what he decides to do. There are a lot of factors to consider before showing a card to a player. Hope this helps.

A 12 year old can referee most hockey games if he or she knows the game, the rules and knows who to skate.
It is just a more challenging team.
