Speculation

What if life is everywhere, but we haven’t found it because there is no land on the worlds it exists on? What if Earth is an ultra rare world in that it doesn’t have deep oceans covering the entire surface.

It would only take another 7 miles of ocean depth to ensure that no spot on the crust of the Earth saw daylight, after all.

It could be that the universe is teaming with intelligent life and it all speaks marine languages.

One third of discovered worlds may be Oceanic planets.
