There are ancestors fooled cradle to grave, there are ancestors that choose to believe anything beyond how life works in plain sight is possible, there are generations of people that just don't want to understand the simplicity of compounding DNA so they follow idealists promising better tomorrows than genetics delivered currently here.
So stupid, dumb, ignorant are really different ways to never accept self as occupying space now collectively in misery loves company of like minded people demanding society stop anyone being honest about about biology keeping genetics to specific numbers alive here now down to how, why, which, what, where, when, whom is on any reality globally denying self evident results of their own collective behavior.
Mind over matter, context controlling content, syllables over substance, metaphors and metaphysical possibilities are better than understanding kinetic ancestral results occupying space now.
What do you know without reciting what others choose to believe? I understand simple compounding DNA while evolving as one of a kind thermodynamically never same form since a fertilized cell..
