Is there???
It's unimaginable there is no other life. If not (movie Contact) "it would be an awfull waste of space"...
Will we detect it???
Remotely possible. I would be thrilled. It would probably turn the world upside down...
Could we communicate???
Apart from the speed-of-light problem, I doubt it. Dolphins are quite intelligent beings and genetically extremely similar to us, but we still cannot communicate a bit...
