Normal intellectual people ignore their natural time evolving currently here living in series parallel displacement conceived to dead, still evolving forward dead to decomposed as their whole cycle occupying space in compounding changes making the past end here and future only developing forward now.
That is called in intellectual circle jerking as alternate realities and parallel universes.
Biology kinetically eternally separates ancestors changing ancestral positions occupying space now. Those not adding replacements become extinct of having their DNA included in ancestors still alive in inverse proportion of their whole position prior to and after conceived.
