Was Earth A 'Water World' 3 Billion Years Ago? New Study Suggests So

As per a new report, scientists recently found evidence that Earth was essentially covered by a giant global ocean that made the planet into some type of “water world” some 3 billion years ago. But did they have slides? (We’re kidding).

Ancient Water World

Chances are the place where you are sitting right now as you’re reading this may be under water around 3 billion years ago, much like almost everything else on the planet. This is because a new report reveals that scientists were recently able to discover some telltale chemical signatures in an ancient slab of ocean crust, all of which point to a planet that had no continents and was essentially covered in water billions of years ago.

But this is just a theory for now. However, if any future confirms these new findings, they can easily help future researchers in refining their theories as to where and how the first single-celled organism first came on Earth. Furthermore, it can also provide significant insight as to what other types of worlds may be habitable based on our planet’s history.

“An early Earth without emergent continents may have resembled a ‘water world’, providing an important environmental constraint on the origin and evolution of life on Earth, as well as its possible existence elsewhere,” the scientists wrote.

The new project was reportedly launched by Boswell Wing from the University of Colorado, Boulder, and his former postdoctoral student Benjamin Johnson, now at Iowa State University, in order to break new ground in the decades-long debate as to what ancient Earth really looked like. Their work reportedly centered on a geological site located in north-western Australia’s outback. At the site, a 3.2 billion-year-old slab of ocean floor had been turned on its side, which was then studied by the scientists in order to unlock the planet’s ancient mysteries. From there, they were able to make findings that point to ancient Earth being mostly underwater.

“Without continents above the ocean, the oxygen value would be distinct from today, which is exactly what we found. And it’s different in a way that’s most easily explained without land to get rained on and without soil formation,” Johnson said.
