The First Rainbow


  It is heralded as "God'sPromise" to Noah, that he would never destroy the world in such a way again.Today we know that a rainbow is a prismatic effect of sunlight througha light rain or fine mist hence the proverbial "pot of gold at the endof the rainbow" (you can never reach the point where a rainbow touches ground, because its appearance is relative to the observer). Many of thelight effects we see in the sky are due to these types of "light bending"or "light filtering" in our atmosphere. From coronas, or halos, aroundthe moon, to most twinkling stars, to the color of the sky itself ~ it all depends on whatthe light is passing through before it reaches our eyes. 

  At the time of the Great Flood, Noah had grown children, but was not yet a grandfather. Still, we  must assume that he had been on this Earth long enough to have seen mosteveryday things. But in order for Noah to have never seen a rainbow before,in his long life, he would have had to have either never encountered rain,or never seen a clear sky. We know he knew what rain was, even before the famous 40 days and 40 nights. Until they landed on Mount Ararat, Noah'sfamily were 
vegetarians ~ and besides, he hadtrees to build the Ark. So we may tenatively assume that the skies were overcast all his life (as hard as that may be for us modern Earthlingsto imagine). Now for someone to have never encountered even a tiny patchof blue yonder or twinkling starlight ~that  is interesting ! 

  Noah ultimately lived to the astounding age of about 950 years. His father, Methusalah, is saidto have tripled that. If the Earth were in such a state that the skieswere cloudy all day, this would push the oxygen content of the atmosphereup to extremely high and healthy levels. Without natural (or unnatural)degeneration of the Human body's internal organs, you or I could quiteeasily  endure as many centuries. As we get older, our heart, lungs,liver and brain all grow tired until enough of them have ceased to functionefficiently enough to keep us alive. Sadly, for all of us, in the end,if we survive everything else, what it ultimately comes down to is simpleoxygen deprivation. 

  If the Earth does in fact change its axial tilt periodically, then it is possible that this over saturatedatmospheric condition could have reigned for a period of several thousandyears ~ which would well explain an abandonment, or eventual atrophy, ofastronomy. If such an ancient culture had found itself without reference to the stars, when they appeared again in the sky several thousand yearslater, they would undoubtedly seem very strange, perhaps like Gods or demonsor countless fixed points of light in a celestial sphere. But if therewere any artifacts or monuments dedicated to such sciences, aligned to important formations, who would know 
what to make of them ?
