The sun is older than the earth, but the water on earth is older than the sun.
Every time you sip a glass of water, you're actually drinking a liquid "fossil" that's far older than human history. The secret lies in a trace chemical called " deuterium ."
Before our Sun was born 4.6 billion years ago, the universe was just a giant, extremely cold cloud of gas and dust.
It was in this frozen environment that the first water molecules were created, long before the center of our solar system began to glow. When the Sun finally "woke" and became a super-hot star, many thought its heat would destroy all the water molecules around it. But that wasn't the case. Most of these primordial water molecules proved remarkably resilient; they survived within the dust disk that would eventually solidify into the planets, including Earth.
Scientists estimate that about half of the water in our oceans, rivers, and even inside your body originated from this ancient interstellar ice. So, Earth's water isn't just inanimate matter, but a silent witness to the birth of our solar system. When you take a shower or brew your coffee this morning, you're actually coming into contact with material that was already there, floating in the void of space, even before the Sun existed to shine on it.
