Existing here today?
conception or birth?
Exiting the womb until entering one's tomb?
Death or extinction?
Evolving is a one directional journey from conceived to dead since every ancestor exists conceived to decomposed between inception and extinction of their ancestral lineage, unless something prevents decay.
why does this apply to politics, religion, economics, every generation gap living regardless past and/or currently alive regardless which generation gap they arrived in life located in this atmosphere?
