john- If anything I'd imagine they would quarantine this space.

I enjoyed that one....very humorous.

It's hard to believe there is not life anywhere else other than Earth. Some say no....but i think yes.......

Yes, there is intelligent life similiar to ourselves in the Universe. It's like that old question, "If a tree falls in the woods does it make a sound if no one is there to hear it, duh!"

Life does not begin nor end with us. Our world began and will end with us, but there are worlds to numerous to mention that begun before ours and will end long after ours is gone.

This does mean that those worlds will have any contact with us, especially if you consider if we would be at the top of their list considering the competition. I'm sure they could visit a new world every day based on their appeal and never get to us.

We have not done a very good job of selling the Earth as a destination point to other sentient life in the universe. I guess you might consider the earth the Afghanistan of the universe, except being of no real threat, or positve interest.

There is sentient life in the universe, but if you were them do you really beleive the earth would be at the top of their list as a place to visit fellow enlighten fun sentient beings?

If anything I'd imagine they would quarantine this space.

The line from the movie "Contact" says it best: "If there's not, it's a terrible waste of space."
