There is more to the universe than just hot planets. I think the earth, and planets such as Mars would clearly substantiate that.
Did you know during nuclear weapons testing that life was found just below the surface close to where weapons were detonated?
Name one extra-terrestial system that doesn't contain close-orbiting giant planets (i.e., "hot Jupiters"). Out of the over 200 that have been discovered, they all contain them. Those will not be life sites, nor will their moons.
This star/planet system, just 127 light years away is practically our cosmic next door neighbor. Star/Planet systems are fairly common, apparently.
The Milky Way has maybe 400 Billion stars, and there are another 100 Billion galaxies out there, each with Billions more star systems. Without a doubt, there is other life out there in the universe.
