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.

Half of Earth’s water formed before the sun was born
Water may be more widespread in planetary systems than previously thought. A team of researchers studying the origin of the water in our solar system has concluded that up to half of it formed before the sun itself was born—that is, in the cloud of dust and gas that was the progenitor of our solar system. If water can form in abundance in such clouds, then it may be found everywhere.
To believe in a universe as young as six or seven thousand years old is to extinguish the light from most of the galaxy. Not to mention, the light from all the hundred billion other galaxies in the observable universe. (Cosmos: A SpaceTime Odyssey)

The Pelican Nebula is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name. [**]
