How did earth get all this water?

I regret having passed an opinion re cometary H2O contributions, because while this is something I have often reflected on, I never came to any conclusion, so really I am very open-minded about it.

What happened was that when I wrote that last post, the last time I'd reflected on the subject, I was thinking about mineral hydrates in the mantle. Earth's mantle has always had a huge capacity to entrap H2O as hydrates despite high temperatures, because of high pressures.

So it is wrong to assume, as many do, that all the H2O would have been boiled out of the Earth, then blown away by the Solar Wind and so on. By the way, I've just revised that w.1a.pps Slide 35 referred to in my last two posts to read:

"Symmetrical MOAC winners indicate real antipodal resonances of Mars, Moon and Earth, consistent with super huge impact-generated shock wave interference pattern fringe "inscription¡°, Freeze Effect geneses of these inner planets¡¯ surfaces. Note that Moon, Mars symmetries indicate that Earth¡¯s symmetries would probably have been preserved by Freeze Effect without its oceans."

This thread discussion (my v.7 Link. Thanks MetaResearch!) has led to my improving the explanations, relevant to the Topic, of my w.1a.pps Slides 36, 35, which now read, respectively:

"That water would have been released into the crusts and surfaces of Mars, Moon, Earth from subcrustal mineral hydrates by those antipodal resonances, along with other light minerals. In the case of the Earth, these would have included much oil and salt. Heavy metals would also have been released from the CMB, because shock wave energy densities would have increased with depth, melting the central core, 4.16."

"[Mars, Moon and Earth] Symmetrical MOAC [global Maps Of Antipodal Conjugacies] winners indicate real antipodal resonances of Mars, Moon and Earth, consistent with super huge impact-generated shock wave interference pattern fringe "inscription¡°, Freeze Effect geneses of these inner planets¡¯ surfaces.
