There is only one stand for the concept of anything else is possible socially cradle to grave life only happens evolving in series parallel space inhabiting time as conceived to decomposed ancestrally alive now?
A cycle of life begins with inception of ancestral lineages and conceptions of subsequent generations in each ancestral lineage geographically present outcomes so far in this atmosphere.
I can think of over 8.2 billion genetic outcomes of current ancestries of humans in this atmosphere with never duplicated chromosomes of binary code 0 or 1 of a kind living in plain sight this or any next rotation of this planet that would show how that isn't historically accurate in current events. No exception by their DNA as to which species they are within now.
