If "they" are there, "they" could be either supremely disinterested in us or they could be sending us an invite in a hyper-luminal medium that we have yet to identify. Why would they be using lasers/radio waves across those same distances we find so daunting? If you have the means to use something a LOT faster, why would you want to wait millinia to talk to a race who is so far below your own tech level?
Things to ponder...
