A new model of the early Earth suggests that until around 2.5 billion years ago oceans covered almost the whole of the planet.
Just 2% to 3% of the Earth’s surface would have been dry land, compared with 28% today.
The Earth at that time may have resembled the way it looked in Waterworld, the 1995 post-apocalyptic sci-fi movie starring Kevin Costner.

Glad to have you aboard this OL' Earth!
