How: Sports or games of any kind are created as soon as just 2 or 3 people are sufficiently agreed on a set of rules such that the idea can amicably be played and tested for viability.
Why: Because they are fun and provide a place/medium for young people, in particular, to invest their energies, develop their bodies and create social environs and so that people can be active and heathy.
Sports have been around since the dawn of man. Ancient Celts did Wrestling matches, the axe tosses, Archery contests ( these are still done today), the caber toss, and throwing rocks as sports. Horses races and gambling games have been around for thousands of years. The Mayans and ancient Incas had a Basketball type sport.
