Solar System's Water Is Older Than the Sun

astroengine writes Next time you're swimming in the ocean, consider this: part of the water is older than the sun. So concludes a team of scientists who ran computer models comparing the ratios of hydrogen isotopes over time. Taking into account new insights that the solar nebula had less ionizing radiation than previously thought, the models show that at least some of the water found in the ocean, as well as in comets, meteorites and on the moon, predate the sun's birth.

Water Molecules

[Roger W Moore]

I believe that they are only considering the water molecules: the hydrogen atoms which make up water will be as old as the Big Bang. However since there are ice-based comets out there I hardly find it surprising that there was water in the solar system before the sun formed. Aren't the comets supposed to be the left over debris from the formation of the sun and planets? So this result seems to be just confirmation what we already knew.
