Beg to differ: my point accepts the costraint of the speed of light. At those speeds, potential signs of intelligent activity (deliberate or not) have had 13.7 billion years to reach us - i.e. emanating from anywhere within a radius of 10+ billion lights years of us.

And it is not necessarily a planned and deliberate communication - it may be nothing more sophisticated that the equivalent of a 10 Billion-year-old episode of the Klingon Brady Bunch arriving here to be be enjoyed by us with no commerical breaks. Electromagnetic spectrum pollution of the kind at which we excel.
