Remember that some of the molecules in your “fresh” sip of water are actually billions of years old—far older than the solar system itself.
It looks doubtful that water existed on Earth before the solar system in which it is located. However, a recent peer-reviewed study published in the journal Science supports this.
Astronomers arrived at this conclusion by demonstrating that water in our solar system had to have been produced inside the huge cloud of gas and dust that preceded and was required for the creation of the star known as the Sun. This implies that water existed before the Sun exploded into a star, water that eventually made its way to Earth via “wet rocks” such as asteroids or comets.
