Consciousness and life after death in the evolution of intelligence

To date, no scientific study has found reliable evidence of an afterlife; the mechanism of consciousness is two of the most challenging questions. Here, I show the hypotheses for consciousness and the probability of an afterlife through three simple thought experiments and theoretical evidence. I hypothesize that when a person or animal dies, the natural selection of the next life within a new nervous system’s physical types might depend on the type of the finally evolved yet unknown particle of the previous life. When a brain dies, the (two-in-one) microparticle might be emitted at infinite speed from the dead brain and simultaneously bond with a suitable naturally selected zygote or early nervous system somewhere in the universe/s and form a new life with the impact of new nature and nurture. Finding alternatives other than the afterlife is challenging, and more studies are needed to precisely understand the theory's mechanism.
