Just another proof that the brain tries to identify faces in everything it sees. Is pretty important for survival, at least, has been. Maybe they should send politicians into the imaging teams. Those are highly trained to remember faces.
If you look at all the different morphologies animals have developed here on Earth, I'd say it's highly unlikely that any aliens morphology would resemble the human one. The difference will be much larger than just a boney forehead...
