The quest for life

I just read that NASA has discovered water in one of Saturn's moon. The Cassini spacecraft sent back photos of what appears to be yellowish colored water shooting out of geysers powered by liquid reservoirs that appear to extend tens of yards beneath the moon's icy surface.

This is a great discovery as it may show signs of life outside of Earth. Further it provides an atmospheric environment similar to that of Earth, so that when Earth becomes overpopulated some could migrate over to Saturn's moon.

What is incredibly puzzling to me is that mankind has always been seeking life outside of Earth, but if there was life don't you think they would have been seeking the same as us? We are sending spacecrafts into orbit, planets, and moons, but we don't have clear proof of others doing the same. Except for those who believe in UFO and the likes.

The bottom line is that even if there is no other intelligent being out there, at least we now have a place to go when we finish screwing up this planet.
