But you see dead is not really dead, it is just an in between state before entering a new human life. Reincarnation from Buddhism, Hinduism, Gnostic Christians, Jewish cults all believed that humans live many lives and the present one is just one of many. Then there is the parallel world they experienced and how they had forgotten the Island world. Interesting ideas played out leaving us with as many questions and no real answers. LOL I loved the LOST show and saw every episode.
