The majority of people are learning life from scratch. From scratch means that they don't consciously use their past life experiences and honestly believe that this is their first and only life. This provides an extraordinary learning experience. People experience everything as if they have never experienced it before. The most important experiences for humans are births (their and of their children), deaths, meeting close friends and mates, falling in love, leaving home and entering the larger world (this happens in stages - going to kindergarten school, going to college, starting to live separately from parents, becoming financially independent, marrying and begetting children).
