Delia Ketchum was once a novice pokemon trainer who retired early to start a family with her new husband, Delia and her husband both had a child who they named Ash Ketchum. One day before he reached the age of 10 he was killed in a terrible accident which split the family apart causing the late ash's father to leave Delia. The death of Delia's son hurt her so badly that she got her ditto she trained when she was a young trainer to transform into her dead son to live out a fantasy that her son is still alive.
Her deceased son always wanted to be a pokemon master so she sent off her ditto (ash) to try to become a pokemon trainer to fulfill that dream in his name which is where the story of the pokemon anime begins...
Ash does not age because he's a ditto who transformed into the shape of a 10 year old boy living out that dead boys dreams.
