Anytime anyone says; "the science is settled" you know the argument is lost, by them. Science doesn't work that way, very little science is "settled". The axiom that all human activity one earth would comprise 36 frames of a feature length movie of earth's history would mean that evidence from 1740 onward would probably be the equivalent of the cuttings and scrapings from a splicer. Hardly enough for even a rough guess under a CSI tech's electron microscope.
