It could also be that we're in a relatively uninteresting part of our local galaxy, on the outskirts of the milky way system. If we develop ftl where would you go first. Besides even if alien species were able to observe the entire night sky, we've only been transmitting signals into space for less then a hundred years.

There is also the hypotheses that everything we send into space becomes indistinguishable from white noise within just 2 light years, which is not even half way to proxima centauri, the closest star to our solar system.

True there's that. We're just beginning to be able to detect planets ourselves. Picking up their radio or tv communications seems a bit far fetched.
We're sending focussed targeted messages into space now though, they should be able to get hundreds of light years out before dissipating. You can send one right now to Gliese526 to arrive there in 17.6 years. http://www.lonesignal.com/

Yet what are the chances that even if someone is out there, that they have a powerful radio telescope pointed at earth to pick up our signals.
