Well I don't think any of us can really answer that with certainty.
But I doubt it.
I believe there are billions (if not billions of billions) of intelligent species in the universe. The problems are... finding, and reaching us. And having the motivation to do so.
The universe is larger, literally, than I can imagine... and believe me, I've tried. When you realize that only a tiny fraction of the stars we know are within traveling distance under the most optimal conditions of conventional (plus a dash of theoretical) propulsion -- that is, within a human lifetime and approaching the speed of light -- you start to appreciate this size.
That's not to rule out the possibility of traversing those distances. There are theoretical means, of which we know little.
But the sheer distances and the colossal number of possible destinations makes one doubt that this sort of thing has brought other beings *here* with any kind of regularity. :-)
I feel sad, personally (at those moments when I can briefly grasp these concepts) that we can never know the awesome beings and events on so many other worlds at this very minute.

I think this question is open enough to be answered with different meanings.
Some people suggest UFO's are evidence of aliens. While I'll agree that UFO's (Unidentified flying objects) exist (I often cannot name every flying thing I see) there is little reason to believe they are from another planet. An intelligent alien species has no reason to hide since clearly their capabilities of going from star system to star system would far outweigh our ability to hurt them.
There are some that suggest microbrial life from Mars may have landed here in a meteorite found in Antartica (AH0004). This is still debatable as to whether or not the microbes found in the rock were living (they are 10 times smaller than the smallest known bacteria on Earth).
I would love to meet a benevolent alien species and learn from them, but without any concrete evidence you can only conclusively say that the answer is "No".

Absolutely....
Just look at Michael Jackson.

We are all aliens, except for you.

Of course.
I am one of them.
Greetings. Take me to your leader. I must destroy him (*cough cough BUSH) for destroying my world.
