Why Do Planets Have to be Earthlike?
It's possible that Earth is actually only marginally habitable by the standards of the universe, says Heller, who points out that our home may not represent a typical habitable world. This is a crazy idea, imagine if there were places that were more habitable than Earth. I can't even imagine, anyone have ideas @jayman?

We have based our model of planetary habitability primarily on the presumption that H2O=life. Yet less than 1% of our water is "fresh" (safe to consume).
