Re: are we alone in the universe?

How about this:

We've concluded that the probability of life starting in the first place is obscenely low. We know for a fact that it has happened at least once though. What if it happened ONLY once? Not necessarily here though. They've found what could be bacteria in meteorites... If I'm not mistaken, they've found such mereorites a couple times. Some planet with life blew up (possibly Superman style) and something landed on earth providing the beginnings of life here. I think we decided that evolution works? If so, to me, that seems probable. Actually, it seems more likely than life starting on multiple planets... Something else that doesn't seem unreasonable to me is some advanced civilization "seeding" earth. If we ever acquire some sort of interplanetary travel, I'm sure someone would try it. (wait...I think that was on an episode of Star Trek...yes it was...but that doesn't change the fact that it's possible) I don't even think we need interplanetary travel. I'm sure Voyager has all sorts of stuff on it. Think of what would happen if it crashes into some earth-like planet. We could probably launch a few thousand canisters of stuff into space. They'll eventually crash into something.
