We know it wasn’t created here over the ages, because natural processes like combustion, breathing and photosynthesis manufacture and destroy roughly equal volumes of water – and either way, the amounts in question are so tiny that they can’t account for all the riches of the stuff on theplanet today.Since Earth’s H2O was neither part of the original package nor created here, it must have came in from far away, on meteoroids or comets or other bodies made in the outer solar system where they were far enough from that ball of fire,so frozen water can exist.
The dirty iceballs, we call comets, are a valid candidate for the source of our water, but they were ruledout when we discovered that they are far too abundant in heavy hydrogen then Earth water.Heavy hydrogen has a neutron as well as a proton in its nucleus. ( Just to let you guys know. ) And forevery million hydrogen atoms in our water, about 150 are heavy ones, while common comet water has twice that many. These different chemical signatures point that Earth’s water could not have arrived on comets.
