*The whole alien conspiracy thing? Turns out it's all true. Extraterrestrials have visited Earth. At least that what Mike Gravel says, and he’s a former senator from Alaska, so he should know. And he knows a lot. It’s dangerous stuff. You may not even want to keep reading. "It goes right to the White House," Gravel revealed this week in Washington, where he was paid $20,000 by a UFO advocacy group to speak at the Citizen Hearing on Disclosure. But how could this information be squelched so effectively, and by whom? "What we're faced with here is, in areas of the media, and the government too, an effort to marginalize and ridicule people who have specific knowledge," said Gravel, who should be marginalized and ridiculed. Trust us. We're the media.

I've a lot about this question.
My current state of mind is this:
1) There is little evidence that faster than light speed is doable. It seems to fly in the face of what every physicist I know says. For it to be possible, there has to be something in physics that hasn't been discovered or revealed to be mainstream science yet. Considering how many smart people do physics, if it is possible to travel faster than light, it probably isn't very likely since no one has shown how it is feasible without do the equivalent of ripping a hole through the fabric of the universe which would destroy anything before it had a chance to arrive at its destination. So I'm not expecting faster than light travel any time soon.
2) Interstellar travel might be possible even without faster than light travel. This could happen if A) the stars were close enough together and B) if sentient beings could live a really long time.
Both actually are possible.
As for A) Most people don't realize the stars can move at 1/10000th the speed of light relative to each other. So over a million years, the stars can travel 100 light years. At one time the constellations in the sky looked extremely different because there were different stars nearby. It's possible that 100,000 years ago some brown star we can't see now was actually quite close to earth...like a fraction of a light year...a travelable distance even with current technology...given enough time. Maybe some aliens jumped from there to here back then.
B) To get around the problem of voyages taking decades or centuries: it's conceivable that some species could live for much longer than humans do...maybe 1000 years for instance. Maybe also computers ran a ship with cryogenic freezing (although I'm not sure if this possible), or, more possibly artificially inseminated some alien eggs as the ship got close to a new planet.
3) While two might have happened, I'm not sure it did in the deep past. There have been some interesting archealogical finds (Gobleki Tepe and Puma Punku) that some claim required more advanced technology than the ancients had but I'm skeptical of this now.
4) If aliens ever visited Earth, they don't seem to have much of a presence now. Maybe they aren't interfering on purpose. If they are out there or not, it doesn't seem to really matter because they aren't around.
I do think life probably exists on other planets. But right now it's not accessible. So we can believe whatever we want.
5) If I were an alien, I'd be kind of scared to visit Earth. People are interesting. But really kind of crazy. And smart enough to be a danger to a lot of species. Maybe also extraterrestrial ones.
If I had to guess, we're going to be alone for a while...even if other species are out there.
And I'm ok with that. Humans should figure out how to make our own little corner of the universe a better place and not be such a mean species. I don't want to see us spreading out there just yet until we can prove that. We're getting better...I think...or I hope.
Um, get back to me in a few hundred years. I'll have a better answer then probably.
