explain if we must die

Death is an inevitable part of life for all living beings. As mortal beings, we must all eventually die as part of the natural cycle of life. Death is a necessary part of the life cycle as it allows for new generations to take the place of the old and for the continuation of the species.

Additionally, death can also be seen as a way to bring closure and finality to one's life. It allows individuals to make peace with their existence and reflect on the meaning and purpose of their life.

While death is often seen as a difficult and painful experience, it is a fundamental part of the human experience. It is important to accept and come to terms with death as it is an inevitable part of life that we all must eventually face.
