And how the hell do you pronounce "Suibhne"?

Sweeney.

And who says that it is or that it has to be in a shape or form similar to us?

What I mean is given to language, culture and technology. Of the millions of species we know of, we're the only ones who do that. Otherwise - I'm way too much of a sci-fi fan to believe in any of this stuff; Quatermass and the Pit makes for a fine film, but not be taken seriously, or religiously, as some people do. It's all there in the sci-fi canon - ad infinitum - but if there is life out there, I'm guessing it'll be more Alien than Star Trek, though I did enjoy District 9.
