Well, as large as the universe is, it would be really selfish and ignorant to think that we, on earth, are the only intelligent beings occupying the universe. There HAVE to be other intelligent beings out there.
Now, whether or not they have ever visited earth is a completely other matter. Frankly, I don't believe they ever have. Any race of beings intelligent enough to be able to build a spacecraft that can traverse such an expanse, then visit our planet, would more than likely make their visit well known to us. The best way for them to study us and learn about us would be to interact with us. I see no reason for them to fly around mysteriously, and abduct us in our sleep and poke big things into our butts.
So, I don't believe in any UFO's that have been sighted as of yet.

I think it is likely that life exists out there. Our planet orbits a sun which is "bog standard", an average sun, nothing special. Logically if our sun is ordinary, there are others like it... and with millions, if not billions of stars out there, well, I think its probable that somewhere there is life. And look at our own planet, life is persistent, and over comes almost everything, no matter how close it may come to being snuffed out. Yes, I say there is life out there.... but intelligent life is another kettle of fish entirely. Maybe, maybe not. Still, if there are smart aliens, not sure if I think they would go joy riding around earth.
look what our planet has accomplished in terms of technology....who knows what we can do in 1000 years time....i think it is impossible that there is no other intelligent life in the universe...i also find it quite probable that there could be an intelligent race with advanced technology that could of visited earth

lol, millions if not billions? There are over 100 billion stars in every galaxy, and there are over 100 billion galaxies in the universe! Big understatement you made.... there are more than 10,000,000,000,000,000,000,000 (ten sextillion) stars.

Whereas I doubt that they'd want to. And it doesn't matter how intelligent you are, you can't think problems like the impossibility of faster-than-light travel away.
