Identity includes the idiosyncratic things that make a person unique. Personal identity is a construct which one continually builds up during the whole life. What you can do and how you see yourself today is made up of what you have experienced in the past. The other part consists of what is still upcoming. Our personal goals and our dreams of the future. Our human identity is located somewhere between the early traces of cavemen in volcano ashes and the future footprints after the colonization of Mars.
