“It’s possible that Earth is actually only marginally habitable by the standards of the universe”

Here is what potential “superhabitable” planets would be like: “most likely older than Earth and two to three times bigger, the researchers say. And they would orbit stars that are somewhat less massive than our sun. Any liquid water wouldn’t be in a giant, deep ocean, but would be scattered over the surface of the planets in shallow reservoirs. The planets would need a global magnetic field to serve as protection from cosmic radiation, and they would probably have thicker atmospheres than the Earth does.” Wait, but what does this have to do with Jesus?
