Where did all the water on Earth come from? It's a question that sounds simple until you realize the answer stretches beyond our planet, beyond our sun, and straight into the bones of the universe itself.
Because here's the plot twist. Earth wasn't born with oceans. In its early days, our world was a glowing sphere of molten rock. Any water that touched it instantly vaporized. Seas, lakes, rain, none of it existed. Yet today, our planet is drowning in over a billion trillion liters of it.
So, where did this impossible flood come from? Part of the answer lies deep in space. Billions of years ago, icy asteroids and comets, dirty snowballs traveling thousands of kilometers, bombarded the young earth. Every impact delivered frozen water and hydrogen like cosmic cargo ships unloading oceans.
The rest came from inside the planet itself. Earth's interior held trapped hydrogen and oxygen. As volcanic eruptions tore through the crust, those gases met, formed water vapor, and rained back down relentlessly.
So every wave, every raindrop, every glass you drink has been on a journey since before Earth existed. You're not drinking water. You're drinking stardust that learned to flow.
