“How do they determine the age of the water?”
Easy. All water is as old as the earth after the original making with the follow on of meteorites. So it’s all old.
That is unless you believe that the joining of oxygen and hydrogen can happen and create new water, then the question comes up how come we don’t have too much water when people are telling us we are running short since there is so much hydrogen and oxygen?
And if we are running short, and all it takes is the joining of two hydrogen molecules and one oxygen molecule, then why not just make some?
God I don’t feel any better now.
