Howdy y'all,
Oh, back to JW-style reasoning. How WE explained the presence of rainbows through all history, even in the Garden of Eden - up till the time of Noah actually observing a rainbow was thus:
The earth was surrounded by clouds (like a "swaddling band", remember?) and the sun didn't shine strongly. And there was a misting (I would assume a lot for rivers to flow) probably every night. (I would also assume the humidity would have been mightily high every night, eh?)
Well, between the misting going back to the clouds, coming down to the rivers, etc., and there not being direct sunshine (as we know it now)......rainbows would not be observed.
However, AFTER the Global Flood, the clouds which had surrounded the earth like a swaddling band were gone - and the sunshine could shiiiiiiiiiiiiine on through........and thus, Noah could - for the first time - *see* a rainbow.
There! Now if you can buy all the other arguments surrounding the rainbow, you can buy my Rainbow Reasoning, can'tcha?
