This
and this sum up my thoughts.
Muppet's sentiments regarding how likely it is that we'll ever see ET life are also echoed by myself. It would be pretty cool. It would kind of throw everything we have up in the air, but it would still be pretty cool. I just can't see it happening, though. How would it even work? It would end up being a case of about five countries all trying to get the aliens to take on their language or something. It's awesome to think about all of this, even with the idea that they would actually stop by, assuming we advance to the point that we can reach beyond the damned moon. I'll start daydreaming about all this sort of thing when man is able to make serious headway towards interstellar flight, let alone interplanetary.
