So far we've seen no verifiable evidence of other sentient species. That said, I believe with some certainty that somewhere in our galaxy at some past, present, or future time, a sentient species did/does/will exist.
Why haven't we heard from them?
Perhaps they are not technologically advanced enough to be heard. They may be mastering stone knives right now, or experiencing their own Rennaisance.
Perhaps they are here right now. Any species sufficiently advanced to travel interstellar distances would be able to hide or masquerade with ease. That Boeing 737 that just flew by may be a surveillance craft.
Perhaps they are so far away they will never notice us and vice versa.
Perhaps they existed a million years ago and died out.
Perhaps they will exist a million years from now.
It is really impossible to know for sure.
The Drake Equation suggests that there is sentient life out there. The Fermi Paradox casts doubt. Play around with the calculation form at the second link and see what you think.

Everytime I thought I saw a UFO, it turns out to be aircraft. But I sure do hope that aliens land on Earth someday, because it'd be nice to know that this isn't the only planet in the universe that can support life :).

Sure and I have survived to talk about it. I can't say the same for the ones who were dissected though. It all seems like a weird dream though.All I have for the most part are the scoop marks and some vague bizarre memories.Some things are better forgotten uno.

I saw a black triangle at night once moving steadily and completly silent across the sky. I saw it clearly with binoculars because I was star-watching at the time. I also have a co-worker who saw lights zig-zagging above the ocean at the beach at night, and took pictures but they turned out blurry. There is no proof of it, though, because they're "unidentified".

Yes. As a matter of fact there is one under my bed right now and it's snoring is keeping me awake.
