What is the explanation of why we have not been visited? One possibility is that the argument, about the appearance of life on Earth, is wrong. Maybe the probability of life spontaneously appearing is so low, that Earth is the only planet in the galaxy, or in the observable universe, in which it happened. Another possibility is that there was a reasonable probability of forming self reproducing systems, like cells, but that most of these forms of life did not evolve intelligence.

Intelligence, Hawking believes contrary to our human-centric existece, may not have any long-term survival value. In comparison the microbial world, will live on, even if all other life on Earth is wiped out by our actions.

People are really too ignorant about the way the Universe is, and how it works that they really have no room to say anything about it.
We speak about UFO's, and alien life, because there is proof of it.
But to just assert that we are the only intelligent life in our universe, or even galaxy is absolutely absurd.
The sheer size of our "visible" or "known" universe, along with the fact that there may be multiverses, and different dimensions, the mathematical probability of our being the only intelligent life force out there is zero.

A very interesting article - Stephen Hawking: Why Isn't the Milky Way "Crawling With Self-Designing Mechanical or Biological Life?" - based on a lecture he gave called "Life in the Universe."

Excerpt - I strongly encourage you to follow the link and read the rest.
He rejects the idea that UFOs contain beings from outer space, but even if you believe that they do you can appreciate what he has to say about the nature of intelligent life in the universe.

How can he talk about the universe, when all he’s known is this tiny little planet in a universe full of billion of galaxies? He speculates what he sees around him like what all humans do. He can’t even ponder what life could be like in different galaxies. Like common we have already found planets that defy the laws of physics in our own galaxy. We don’t even know what other galaxies would be like.
Cognitive Dissonance
Cognitive dissonance is an uncomfortable feeling caused by holding two contradictory ideas simultaneously. The "ideas" or "cognitions" in question may include attitudes and beliefs, the awareness of one's behavior, and facts. The theory of cognitive dissonance proposes that people have a motivational drive to reduce dissonance by changing their attitudes, beliefs, and behaviors, or by justifying or rationalizing their attitudes, beliefs, and behaviors.
