I'm not usually a big fan of most traditions. I guess some have their place.
Crossing over to where we've never been before, most of the things we ever knew just fall to the ground.
I think Oppenheimer saw something there that influenced him to make that famous quote.
I have another source that mentions a nuclear event that caused the flood.
These may contradict traditional Bible beliefs, but they don't contradict the Bible itself.
The Bible said God would destroy the world.
He does many things though man.
It could be God in man that let him begin to unravel the mysteries of the universe in the first place.
It said the present world was being reserved for judgement by fire and "As it was in the days of Noah, so would it be at the coming of the Son of Man."
Is it such a stretch to believe man could destroy himself?
Perhaps it wouldn't be the first time.
The fact it was recorded somewhere else like the Vedas lends more credibility to the account in my opinion. Not less.
But you're right, that's not a traditional Christian view.
You would worship a god that makes mistakes, that solves them with nuclear weapons? That is not even a god, but simply a more advanced life form?
