To quote Enrico Fermi: "Where are they?"

Most are either in hiding or were destroyed in war. The universe is likely a very bad neighborhood and advanced life learns to not advertise their existence. Food searching is not enough evolutionary pressure to develop advanced intelligence, it requires the discovery of war, which is the catalyst for the next level of evolution to occur. Intelligent life and a war making disposition go hand in hand. We may find intelligent life out there someday, but they will probably kill us.

If habitable real estate (meaning right temp, gravity, no need for domes or tunneling, etc., etc.) is real scarce, why not break out the neutron bombs? Wipe out the natives and their biosphere, and replace it with your own, especially if they can't shoot back.
