Consciousness and life after death in the evolution of intelligence

To date, no scientific study has found 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. The consciousness can be discussed based on a new theory that when a person or animal dies, the selection of a new nervous system's characteristic of a new life might depend on the characteristics of the final evolved yet unknown particle. Here, I suggest that the evolution of the said particle depends on the natural evolution of cognition. The fittest intellectuals survive happier; when a brain dies, the two microparticles might emit at infinite speed from the dead brain and simultaneously bond with a naturally select suitable zygote or early nervous system somewhere in the universe/s, forming a new life with the impact of new nurture.
