If true, the Earth couldn't have been where it is now--Lee:

I believe that water from the collision is all over the area between Mars and Jupiter It's on the asteroids, it's on the Moon, it's on Mars. it's on the comets. I call that the "fingerprints" of the collision.

Water from the Sun?
As with science more generally, the Dark Star website has been debating the origin of Earth's water for a long time (1). What's unusual here is that the anomalies thrown up by the Earth's abundant oceans form part of an argument about the origin of the planet itself. Put simply, the Earth is too close to the Sun to have so much water remaining on it. The water should have been blasted away long ago by heat and the action of the solar wind.
Scientists have long answered this using the 'late veneer' hypothesis whereby water is deposited during the impact of water-rich asteroids and comets. It's a complex offering, with a competing but allied concept of 'late accretion' to consider (2). Either way, the chemical composition of water here on Earth - and among the asteroids and comets most likely to have caused this water-dump - don't match (3). Instead, Earth's water more closely matches asteroids located in the outer asteroid belt.
Picking up on Zecharia Sitchin's notion of a migrating Earth - following a collision during an encounter with a rogue Planet X body and its moons (4) - the whole mystery could be resolved in an Occam's Razor sort of way by assuming that Earth formed where the asteroid belt currently is. Indeed, the belt itself may be debris from the cosmic encounter with the rogue planet, containing chunks of our own planet. The concept of migrating planets is hardly new. Indeed, much of our current cosmology rest upon it (e.g. the Nice model). Earth's formation in this zone would likely require Jupiter to have formed a bit further out, but this is hardly beyond the realm of possibility either.
Recent scientific work may offer an alternative explanation - at least partly. Instead of comets and asteroids being the vectors for water delivery, how about the solar wind? Space dust is prevalent throughout the solar system (seen in the so-called zodiacal light'). The action of the solar wind can ionise hydrogen into protons, allowing chemical reactions on the surface of dust grains which can lead to the production of water. This concept has been used to account for anomalously high water content distributed within the dusty regolith on the Moon's surface
"“We think of water as this special, magical compound,” said William M. Farrell, a plasma physicist at NASA’s Goddard Space Flight Center ... “But here’s what’s amazing: every rock has the potential to make water, especially after being irradiated by the solar wind.”" (5)
That chemical activity also appears to be happening on asteroids. Scientists examining samples from Japan’s Hayabusa spacecraft mission, which brought part of the asteroid Itokawa to Earth in 2010, have determined that the isotope ratio of water has been unexpectedly skewed (6). They consider this to be a result of the action of the Solar Wind providing an 'additional isotopically light reservoir' of proton-rich hydrogen ions, and thus water:
"We used atom probe tomography to directly observe an average ~1 mol% enrichment in water and hydroxyls in the solar-wind-irradiated rim of an olivine grain from the S-type asteroid Itokawa. We also experimentally confirm that H+ irradiation of silicate mineral surfaces produces water molecules. These results suggest that the Itokawa regolith could contain ~20 L m−3 of solar-wind-derived water and that such water reservoirs are probably ubiquitous on airless worlds throughout our Galaxy." (7)
It's a big jump from this finding to water generation on a planet wrapped with a significant atmosphere, like Earth. After all, the chemical reactions take place on the rock which, on Earth, is shielded from proton bombardment. Further, water created during the primordial Earth phases would be subject to drying activities by the Sun. This abundant delivery system should also have profound repercussions for water on Mars, surely?
At the moment it seems reasonable to conclude that Earth's weird water remains an anomaly.

Thanks Andy. Having a bad day with tenents and stuff and this made me smile. Yeah though Jupiter is indeed a totally different animal.Saturn gives us a little hint with its polar shape. Hexagonal? That's not possible with standard physics. But when you look at physics in the way the Sumerians did it gets a lot clearer as they account for matter more as a duality, even with planetary mass. This also rings true with mars, the gravity calculation I did showed a low gravity figure that I concider the neutron plasma core just to try to fit it to something modern science can understand, this too was proved by mars express showing a mag field at the north pole still quite active but very low at the South pole allowing for oxygen to flow off into space.There are many many answers out there we just need to look objectively and without this mainline blinkered vision of reality.Seeing is believing and that's the only way I think mainline will learn. But then it maybe too late and we got the next extinction level event and we go back to stage 1 caveman living and start all over again.It's a shame but seems to be factualKind regardsWayne
