One of the best ways to present the veracity of the Bible’s narrative about Noah’s Flood to your spiritual prey is to paint the picture of the Ice Age; dense cloud cover then, expansive, for all the snowfall in the extreme latitudes as well as the high elevations and much more rainfall in the middle latitudes and low elevations. Of course only the world ocean warmer having been heated from below could have been the engine to have caused such greatly increased evaporation for the expansive ice age cloud cover, in the aftermath of Noah’s Flood when the ocean on average was 80 deg. F., the end of the Ice Age when the ocean had cooled to about today’s average 50 deg. F.
