It has to be an ongoing project. We didn't start projecting signs of life into the universe until, what, 150 years ago?
There are no solar systems that close to us by a magnitude of I don't know how much.
Besides one burst from the Araciebo (spelling?) satellite dish, there has been no big attempt to contact extraterrestrial life (except God and angels). Radio waves from television, radio, etc. would dissipate.
Mayhap, there is nothing or nobody out there?
