This article suggests that a significant portion of Earth's water predates the formation of the Solar System. How could this be possible?
Robert Frost:
Our solar system is not the first of its kind. It formed from a massive cloud that held remnants from a previous solar system or even multiple systems. After the cloud condensed to create the Sun, it likely captured material from passing objects, potentially ejected by a supernova.
At the farthest reaches of our solar system lies the Oort Cloud, a region filled with leftover debris from the formation of the Sun and planets. Some of this material is captured, while some originated from the cloud. Occasionally, gravitational disturbances send a comet toward the Sun, and these icy bodies may have collided with early Earth, delivering the water that now fills our oceans.
The water in our oceans could be leftovers from previous solar systems, predating the formation of our own. Our oceans might have once existed on other planets, where alien civilizations could have sailed across them, consumed them, and even processed it through their bodies. That bottle of water you’re drinking right now, as you read this, might contain water that’s been around for seven billion years, possibly even alien urine.
