Like anyone with an ounce of intelligence, I'm intrigued by the possibility of life - intelligent life - beyond our solar system.
There's something in human nature that cries out for companionship, curiosity, the hope (and fear) that other alien beings are out there and may be somewhat like us.
The SETI institute (Acronym for the SEARCH for EXTRA-TERRESTRIAL INTELLIGENCE) has been watching the skies for decades and not detected anything that would definitively indicate we share the universe with other sentient beings. Well, not detected anything EXCEPT for the "Wow!" signal. Which, exciting as it was, in the end conclusively proved nothing. It was non-replicable, despite repeated listening attempts it did not recur and the source of it remains an enigma.
At the time of the listening it was imagined that any sufficiently advanced interstellar civilization would use radio waves to communicate - hence the listening with radio telescopes. However times change, and in a scant few decades we've seen our own radio signature drop so much that we've become ourselves almost invisible, and we may need to consider that other intelligences may have followed the same trajectory and found other, more efficient means to communicate. We may be looking for intelligence in a very narrow window defined by our own limited technology. Other possibilities for interstellar communication might include an interstellar beacon which would, via quantum entanglement, deliver information instantaneously between stars or remote points. And as our technology we'll doubtless evolve we'll discover other possibilities.
