Looking for a New Planet to Inhabit?

Is there anybody out there?

It was announced today that the NASA Kepler space telescope team has discovered two planets that closely resemble planet earth.  One, named Keppler 20F is particularly interesting to scientists because they suspect that at one time it could have been habitable, after noticing signs that there could have been liquid water on the planet.  At this time they too close to their sun to be inhabitable, but we can certainly prophesize about the kinds of life that once populated the planet.

One has to wonder, if this search is an endeavor to find the human race a new planet in which to reside.  Few will dispute that we have destroyed much of the resources that have sustained life, and we are working on depleting that which remains.
