I realised earlier that DNA allows for all the things we used to use fiction and religion to describe. Re-Incarnation and time travel are there within people's genes passed on to their offspring. I think they will find that both desires and aptitudes, personality traits etc are there too along with the physiological instructions. The supposedly airy fairy hippy idea that we are all one is indeed true as is the fact that we are also actually the living embodiment of our individual ancestors. Great-great-great-great-great-great-great-grandaddy Joe is in many senses walking around the planet on your feet and seeing out thru your eyes, thousands of years after he died. He therefore has the potential to be in Heaven and Hell right here on little old insignificant earth. For some heaven is a bowl of hot food and for others Hell is not being able to give that to their own kids.
