What do you think the "stones" may be ?
Sounds like something from a science fantasy novel, but I would not outright deny that there may be/have been advanced races, Gods we would call them, who had meta-materials with undreamed of powers. In a Universe that may be eternal, and where matter seems to anti-entropically arrange itself into ever more complex forms, who can imagine what types of beings may have been created?
I'm not familiar with the tales of Enlil or Ninurta, though the names I recognise, and not much up on Greek legends, but from what I have read, mainly by Plato about Critias, Timaeus, Socrates, the tales just seem to ring true with me. That there is cross-correlation with some Biblical accounts adds to my beliefs.
So in a nutshell, the Earth undergoes regular, periodic destructions, some of which leave no survivors. I suspect the disasters are natural (CME initiated), though again I wouldn't discount that there may be or have been beings with the power to create and destroy worlds. Plasma/electrical engineering on a very large scale doesn't seem an impossibility to me.
And after a total destruction, we were re-created. Again, not difficult for me to believe given the present progress of humans in that direction. Then cared for and nurtured until we were on our feet again, only to be seen to once more sink into the depraved kind of behaviour that was our original undoing.
And based on my interpretations of what I have read, those cyclical destructions are pretty regular, and one is due any time between now and the next 200 years. We may have a few days warning if the signs of the Tribulation occur as prophesied, and those will be the signs that the Sun is about to have a major CME (or CMC, Coronal Mass Creation)event. Perhaps in some cases a few people, on the side of the Earth away from the blast, could survive, and did so according to the Greek tales, but the history of past civilisations would be lost, as I believe has happened.
The legends recorded from many civilisations around the world I believe may have been implanted at the time when humans were being assisted in their recovery, as the nature of those legends and their telling creates a self-correcting story that can be passed down almost indefinitely while retaining the proper information, a feat that in itself suggests involvement of a higher level of understanding of language than should have been present at the time. So, slightly OT is fine with me in this case, as I think the tales point us in the direction of the true nature of the Sun, as the Creator and Destroyer, by way of the mega CMC/CME. Creating matter from pure light in the lab has been achieved, so the idea of the Sun being able to produce matter, especially during CMEs should not be questioned.
The Gutenberg version of the Critias tales is the one I'm most familiar with:
