Mar 4, 2015 at 16:56 comment added David Hammen Until science gets beyond the stage of extrapolating from a sample size of one (the Earth), the right answer is "We don't know." We need better science to look at the exoplanets that might support life to see if they do indeed support life. Right now, there are too many unknowns. The story of the drunkard looking for his keys under a streetlight comes to mind.
