Galaxy Song - Monty Python
"Whenever life gets you down, Mrs. Brown
And things seem hard or tough
And people are stupid, obnoxious or daft
And you feel that you've had quite enough"

"Just remember that you're standing on a planet that's evolving and revolving at 900 miles an hour
That's orbiting at 90 miles a second, so it's reckoned, the sun that is the source of all our power
The Sun and you and me, and all the stars that we can see are moving at a million miles a day
In an outer spiral arm, at 40,000 miles an hour, of a galaxy we call the Milky Way"

"Our Galaxy itself contains a hundred billion stars, it's a hundred thousand lightyears side to side
It bulges in the middle,16,000 lightyears thick but out by us it's just 3,000 lightyears wide
We're 30,000 lightyears from galactic central point, we go round every 200 million years
And our galaxy is only one of millions of billions in this amazing and expanding universe"

"The universe itself keeps on expanding and expanding, in all of the directions it can whizz
As fast as it can go, the speed of light you know, twelve million miles a minute, and that's the fastest speed there is
So remember when you're feeling very small and insecure how amazingly unlikely is your birth
And pray that there's intelligent life somewhere up in space coz there's bugger all down here on Earth"

Or maybe we can't handle the truth. If they have actually jumped the celestial gap they must process some sort of intelligence one would hope. Maybe we as a species aren't ready for this kind of knowledge. Sighting have happened all through history, keeping an eye on us so we don't spread to the stars until we can control ourselves?

If I came across a village in the jungle that was just as likely to kill me out of fear as anything I mightn't show myself too eagerly either.

Of the potential planets in the galaxy, how many could probably support life. Of that number, how many probably have life. Of the planets that probably have life, the number that could probably support higher forms of intelligent life. Finally, the probably number of civilizations in the galaxy with higher forms of intelligent life. In each case above, the percentages were low, i.e., number of planets that probably support life was something like 20-30% of those that could support life.

OK, the number of civilizations in the galaxy with higher forms of intelligent, according to the was...50.

Oh yeah, by his definition, humankind on the planet Earth was NOT a higher form of intelligent life.
That basically is the essence of the Drake equation. The only problem is, none of those probabilities are known. We can only guess. Most of them, we can't even really grace the guesses with the title "estimates." Depending what you guess, you get a number somewhere between 0 and infinity. Someone earlier in this thread linked to a write up on the Drake equation that you might find interesting. Drake was the guy who came up with it, but I wouldn't be surprised if it was Sagan doing the interview you're referring to.

Playboy writes about stuff like that? Do they do any better at getting basic details right than CNN?

As far as we know the universe is not infinite but is vast. Hence it seems likely to me that life having arisen once could quite probably arise again. Unfortunately (or maybe fortunately) we will probably never meet our contemporary aliens since the probable immense distances between us will make contact impossible. Our civilisations will rise and fall ignorant of the existence of the others. Unless that is the warp drive turns out not to be merely a convenient device of sci-fi writers to overcome the inherent impossibility of interstellar travel (which hampers plot development horribly)
This post is the ticket right here. Itelligent life is unlikely to be around at the same time as us humans due to the fact that soloar systems have been forming at different speeds and times for untold milenia. Whole races could have evolved and failed countless times before our planet was much more then magma. My guess would be that in a billion years we will be one of those races that some civiliation on the other side of the universe is wondering about if we ever existed.

although, our planet is definetly not sitting quiet in space. We have been sending out raido signals for nearly a hundred years straight. So many millions of signals are sent out into the void of space ever minute.
Im not a real expert so i dont know if radio signals disinigrate or fade after time but assuming they dont they would have to at some point in time reach another galaxy and anyone that might be there.

How do you not know that nukular weapons aren't in the contingency plan anyway? They would have to sanitize the experiment at some point anyway. What better way than for it to clean itself?

Yeah. Universe [whatever THAT is] is a big place, it's got lots of time to play with, and all the 'right stuff' for it is already in place. That's a lot of throws of the dice.

BTW, what's 'intellegence'?
