Human Evolutionary History

It is a purely fictional novel; it cannot be substituted into reality; I am walking step by step; but I don't know the specific direction; I can only walk step by step. Walk through human life from the perspective of the protagonist; watch human beings constantly make mistakes and move towards the right path; where is the final direction... Are human beings all the same? No way of knowing. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
