Life happens by combined results never duplicating details arriving next now that occupy time in series parallel proportions of each generation gap living since inception of the ancestral lineages present.
It is so specific the universe is perpetually balancing past results, current events, what remains individually existing next rotation of the planet here now.
Theories and theologies practiced every generation by every ancestral lineage of this species native to this universal location been balancing outcomes this rotation last billion revolutions around the star in this 15 billion year old galaxy among every other galaxy existing each rotation of this planet.
Comparing cycles mutually present in ever changing form as arrived existing in series parallel proportions of occupying space specifically doing what happens next as a whole spontaneously compounding contracting results never duplicated becoming details never the same again. i.e. evolving in plain sight as specifically living eternally separated now as ancestrally positioned since conceived.
Anything else is people make believe life isn't self evident in each alternate reality created separate world orders by geographical locations present evolving at the same time no lifetime ever gets duplicated another generation gap than existed in so far adapting to the moment here.
Hypothetical scenarios, theories, theologies direct outcomes for each incoming great great grandchild repeating the same beliefs as their previously existing contributors to each great great grandchild's one time event of occupying space so far.
Intellectual divide by philosophies, controlling all 5 generation gaps living psychologically, training each brain academically and artistically to politically and spiritually to perform by social consensus and economic outcomes each rotation of the planet measured by comparing total sum past against each ancestor of each generation gap living forward now.
Pick any reality that existed historically or last 7 generation gaps population doesn't expand larger than current 6 generations added so far. Time between each arriving great great grandchild becomes 1 of 4 grandparents or not.
