Genesis Chapter Nine
12 And God said, This is the token of the covenant which I make between me and you and every living creature that is with you, for perpetual generations:
13 I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth.
14 And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud:
15 And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh.
16 And the bow shall be in the cloud; and I will look upon it, that I may remember the everlasting covenant between God and every living creature of all flesh that is upon the earth.
17 And God said unto Noah, This is the token of the covenant, which I have established between me and all flesh that is upon the earth.
The essence of thought is "no cloud - no rain, no cloud - no bow". A very plausible conjecture, unless sunlight had been so diffused prior to the flood that no bow could form (which that scenario would not make as much sense given the vegetation coverage on the earth). Even in a greenhouse, one can form a "bow" by spraying water into the air.
Have you ever heard of the hydrogen theory?
I don't believe I have heard of the hydrogen theory. I do know that Peter says man is willfully ignorant of the fact that we do not live in the same world as pre-Noah. Same earth yes, same world, or conditions no.
I can't remember the chapter and verse but it goes something like, "for this they are willingly ignorant, that the world that was then, standing in the water and out of the water, perished, and the world that is now is reserved for fire and the judgement of ungodly men.
It is a verse that causes me to puzzle the possibilities of it's meaning ecologically.
