If you're asking what the purpose of the afterlife is, its a pretty complicated answer. The Afterlife has very different meaning and descriptions in many different cultures and beliefs. One thing always stays the same throughout though, its a place where people go after they die.
"The Afterlife (also referred to as life after death, the world to come, rebirth or reincarnation) is an existence in which the essential part of an individual's identity or their stream of consciousness continues to live after the death of their physical body."
