Our planet Earth is old. The Sun is old. But there's one thing that might be older than both- the water that we drink. How is this possible?
A prevailing theory has said that water originated on Earth from ice specks floating in a cosmic cloud before our sun was set ablaze. Calculations by astrophysicists state that as much as half of all the water on Earth may have come from that interstellar gas.
The age of water on our planet is about 4.5 billion years, as old as the Solar System itself.
