Cricket was invented in Southeast England, likely during Saxon or Norman times (medieval period), with its earliest definite reference dating back to a court case in 1597 (Old Style, likely 1598) regarding a game played in Guildford, Surrey. Originating as a children’s game in the Weald region, it became an adult sport in the early 17th century. 

Origin: Developed by children in the Weald area of Kent and Sussex in southeast England.

Earliest Reference: Evidence in 1597 shows "crickett" being played in 1598, according to Wikipedia.

Early Evolution: By 1611, it was established as a sport for adults. The game was primarily played in the south of England during the 17th century.

Formalization: Laws of cricket were codified in 1744.

Name Origin: Derived from the Anglo-Saxon word cricc (meaning shepherd's staff), according to Vedantu.
