When the physical human body completes its cellular evolution and reaches the end of its life cycle, the biophysical and chemical elements that our body's are composed of are organically broken down in mass and density to their most minute molecular levels and used as a source of energy for other living organisms which exist within a microscopic realm.
These living organisms which exist within this microscopic realm are of the simplest and least complex forms of life. They too are living and evolving and completing their own particular life cycles.
Death is an end, not a beginning as some religious dreamers would have you believe. There has never been anyone who has returned from the grave and had their experience documented by modern science. All such stories of resurrection and after life adventures have come down to us from antiquity, as legends and superstitious, religious fantasy stories, none of which can be substantiated.
Experiences of reincarnation and the belief that the soul must pass through various stages of evolution to reach a higher plane of existence can be dismissed as Hereditary Memory Transfer, a new science discovered by the researchers at the Subliminal Institute Of Human Consciousness. Hereditary Memory Transfer, is the passing of memories through the genes of ones ancestors.
Modern science now knows beyond a shadow of a doubt that there is no life after death. With this in mind, it is of the utmost importance that one lives their life to the fullest, and shares their love with the world around them. There will be no judgment day by any imaginary God and there is no such thing as sin, so therefore, one should live a care free existence, free of guilt.
If you feel the compulsion to worship something, worship the world and the people around you. If you need to pray to someone, pray to yourself and forgive yourself, after all, when you die the only thing that you can expect is that your descendants will cherish the memories that you pass on to them, and that's all.
Job:7:9: As the cloud is consumed and vanisheth away: so he that goeth down to the grave shall come up no more.
