Football officials used the bladder of an elk before whistles were invented. It would make a sputtering noise similar to that of a struggling engine trying to turn. This practice ended when referees continuously got sick from the Infectious Diseases that would come out of the bladder. They then tried using the horn of a ram, similar to a Shofar in Judaism, but that was too difficult also, thus making the wood Flute the final tool used to call attention and stop action during a game. The flute could only be made of Cherry or Oak wood, however, because other woods had too high of a splinter factor. Other ideas that were tried when the whistle was developed was putting a beetle or bumble bee in the wood flute with a tiny ball of cobalt and blowing it. The cobalt's vibrations would cause a high pitched noise to echo from the insect but that would often lead to the implosion of the critter's internal organs due to the concentration of the noise/vibrations and pitch. Eventually, they got it down to a metal base with a wood ball on the inside, thus the modern whistle was born.

The real name for Soccer is Football. You use your foot, to move the ball. Football was invented before American Football, the rules were written before American Football's rules. American Football shouldn't be called Football because the foot is barely used.

There are usually four officials controlling a soccer match: one Referee, two Assistant Referees, and a Fourth Official. In non-professional games, the Fourth Official is usually not present. In some youth games (U10 and below in the US), the offside law is not applied, and so the Assistant Referees are also not used. To confound things more, there is a FIFA sanctioned experiment in the use of two Additional Assistant Referees stationed near the goals (one on each side). There may also be Reserve Assistant Referees who take no part in the match unless an Assistant Referee is unable to continue.
