Consciousness and life after death in the evolution of intelligence

It seems that no scientific study has been able to find evidence of an afterlife, and the mechanism of consciousness is two of the most challenging questions. Here, I show a hypothesis for consciousness and the probability of an afterlife through three simple thought experiments and theoretical evidence, yet more studies need to precisely understand the mechanism. I found that consciousness might be discussed from three fundamental theories: (1) quantum-level particles of functional neurons in the brain according to quantum mechanics, (2) the brain and its large larger matter than quantum particles behave to general relativity, and (3) a new theory is needed for the function of two ultraquantum particles. When a brain dies, the ultraquantum particles might emit from the dead brain and simultaneously bond with the suitable early vacant nervous system anywhere in the universe/s, creating a new life with the impact of new nurture.
