To be fair, the SETI people kind of ruled out radio-emitting aliens as the source.
"Aliens did it" is still the worst explanation. It just happens that we ruled out all a lot of better ones.

That just means they're not aiming a tight radio beam directly at us. But I don't see why they'd be doing that anyway. Aliens that are not trying to talk to us are still a possibility.
Filling in knowledge gaps with the the word "aliens" is a laughably childish approach to science in my opinion.
There is no reason to believe that God(s) exist. Someone who claims that they do has the burden of proof.
There is also no reason to believe that we Earthlings have the universe all to ourselves. It is an extraordinary claim to suggest that we do. Someone who makes such a claim also bears the burden of proof.
The idea that gods and Type II civilizations are equally implausible is, to put it bluntly, ridiculous.
You are talking about probability of life in the universe based on a tv show, replace aliens with "earth is round" and you will see how ridiculous it sounds.
