Creating the concept of eternal soul to each sole reproduction ever lived adapting to space in this atmosphere only existing as genetics eternally separates reproductions left alive now.
Lot of people have to activate their instinctive brain to answer the question in the title of this thread. Every reality has failed since dawn of civilization but people never stop defying the natural process sustained within a perpetual balancing universal moment with limitless variations of what arrives next now using same periodic elements changing forms shaped inorganically and ancestrally here at the same time showing up with DNA never same reproduction again and last ones added resemble their previous 4 generation gaps most often. 93.75% unique DNA comes from previous 4 generation gaps.
Cannot repeat that enough since nobody accepts it believing life cannot be limited to genetics eternally separating ancestors left alive now.
