Quite possible their planet may have died, or their sun may be dying.
It would make sense for a being to colonize our planet. They'd probably need to wipe us out, and change our environment to suit them. Maybe they are high oxygen beings and require our planet to be saturated with very high levels of oxygen very much like in the prehistoric times. Either way, we're doomed.

Great thread!
This is the point I've been trying to make on the "Climategate" thread.
Our Sun will eventuallly go nova and destroy this planet.
Instead of worrying about Global Warming which will happen anyway, as the Sun heats up as it ages thereby warming the Earth, we should be developing our space travel capability in order to escape this doomed planet.
