Philip touches upon an interesting problem here when he says that before the Flood there was no rain. However, because of the way that the water cycle works (mentioned in Eccl. along with geocentrism), this could not have been true. Neville No problem Neville A closer read of Genises reveals that God used the rainbow as a sign to remember His covenant not to destroy by flood again. This did not say explicitly that it was the first rainbow. Hence rain has always been . I had read years ago, and believed, erroneously, that this was the first time a rainbow had ever occured.. such is a childish myth apparently, as my reading today shows no such thing. The evangelical documentary was Bible based, and was the same documentary which gave me the idea of the water above making a lenze in the atmosphere, where they claimed the stars were more brilliant preflood. You dispensed with this claim before. I retract my words and will reajust the overview. Philip. 13 I will set my bow in the cloud, and it shall be the sign of a covenant between me, and between the earth. 14 And when I shall cover the sky with clouds, my bow shall appear in the clouds: 15 And I will remember my covenant with you, and with every living soul that beareth flesh: and there shall no more be waters of a flood to destroy all flesh. 16 And the bow shall be in the clouds, and I shall see it, and shall remember the everlasting covenant, that was made between God and every living soul of all flesh which is upon the earth.
