Science loves to upjump their theories to the rank of fact, quite often in fact. We haven't even fully explored our own damned solar system so I find it highly suspect that anyone on Earth can say with any degree of certainty as to what sorts of life may or may not be out there in a universe so vast it's beyond insane.
