In the present study, a new sport was created by combining three sports: swimming and diving, gymnastics, and football. This research was developed for the first time after the 2021 Tokyo Summer Olympics. The facilities required for this sport include indoor swimming pools, rings (gymnastics), aquatic life balls, and two hexagonal goals. First, a brief description of the history of gymnastics, swimming and diving, and football is presented as an observation of the theory. Then, the relationship between the mentioned sports and the new sport of aquatic life, in order to identify the pattern of the theory, and then the rules of the new sport of aquatic life, as theory development, are discussed. Aquatic life is played in such a way that the gymnasts of each of the two teams are lined up in the middle of the swimming pool. The ball is thrown by the competition judge to the center of the swimming pool. The gymnasts of the team who have the ball without committing a foul swim from the imaginary line in the middle of the swimming pool toward their goal. Using the rings (gymnastics), they are pulled up and reach the upper space of the swimming pool and jump to other rings (gymnastics) by swinging. The gymnasts then do a keepie-uppie with their feet on the ball. The game is played by passing between the gymnasts and scoring according to the rules of the game.
