To date we have not picked up any signals from aliens. Some take this as a sign that we are alone in the universe or that intelligent life and culture, if it exists elsewhere, is rare.
What I am not clear on is what we are expecting to find.
Reversing the argument, if aliens were searching the heavens for us how close would they have to be to be able to deduct the electromagnetic radiation we have been inadvertently sending over the past 100 years or so?
