  • During the overthrusting, which may have taken a million years, and during the millions of years since, the frosts have chiselled open and the rains have washed away all the overthrust strata, the accumulations of the geological ages from Algonkian times down, except only that one bottom layer.

  • *Instead of a debate on something as ridiculously and ambiguously broad as Creation versus Evolution, why not argue much narrower topics as how overthrusting the Matterhorn in Switzerland works, the science of pollen grain and atmospheric isotopic analysis in mud- and ice-cores, how the bacterial flagellum evolved, how invasive species are displacing the native flora and fauna of the Hawaiian Islands, the first bilaterian flatworms, magnetic evidence for sea-floor spreading, related species on opposite sides of the Atlantic.
