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?

why not? no need to think in terms of what we already know
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).
I guess you're right, but its hard to imagine for sure!
do you think there may actually be non-carbon based life
