This assumes that intelligent life uses radio waves for communication; that these radiowaves are powerful; that despite being powerful they are non-directional. Those are all powerful assumptions. On what basis do you make them and justify them?
You also assume that the alien intelligences want to communicate. They may have learnt it is best to keep very quite, to avoid being absorbed by the Borg.

On what basis do you make this claim. Most 'experts' would disagree with you.

Gravitational did not say we were the third series of intelligent life on Earth, he said we could be. There is a very important distinction between those two, that goes beyond mere semantics.
Moreover, Gravitational did not say that we might be the 3rd series of fecund, technologically advanced, intelligent life on th eEarth; only that we might be the 3rd series of intelligent life. Do you see the difference?
I think he is stretching it a bit with
third series, but I would be loathe to rule out an earlier inteligent species amongst the theropods. Bi-pedal hunters, with an outstanding record for adaptability to varied environmental conditions - a perfect source for an earlier intellect.
