Infinitely more likely there is a lot of intelligent life
I expect they could be but the huge distances mean we'll probably never hear from them.

It's almost a comforting thought that. Like the thing on Star Wars where they don't communicate with another species if they don't possess warp capable technology.

what channel is this on? it's hard to find when online 
Wow.
Acidhell2 is right, they practically are plucked out of thin air. Sure we have a rough idea of how many stars there are in our galaxy, and how many galaxies there are. But the rest is guess work.
How can you possibly say they are accurate when it hasn't been proven? They are guesses.

it was on Discovery channel.

A coin can come up tails a million times in a row, doesn't mean heads is any more likely to come up the next toss than it was the last.
You should never rely on probability.
I saw it tonight on Channel 4 at 8pm. You can watch it here if you like:

lol. According to the Drake equation there could be ~10,000 'communicative civilizations' in our Galaxy and there are +100 billion galaxies

yay
Only if you put stupid numbers in there. In fact, show me how you reached that number.
Yes of course, I am Drake and I made the equation

also please elaborate on what you mean by "stupid numbers". It would be really interesting to hear your well researched opinion

The Drake equation is just that, an equation, you have to fill in the numbers. How could you possibly say 10K advanced civilisations exist in our galaxy from the Drake equation?
Stupid numbers = Stupidly high numbers.

There's probably aliens having the same debate right now.
that will be Star Trek

Idiots debating life on a computer hardware forum during Saturday night?
Right on the other side of the galaxy?
Universe is doomed.
Yeah googled it afterwards.

When exactly did I say 10k DID exist?
You can put conservative numbers into the equation and still come up with a lot of life in our galaxy
Mathematical probabilities are 100% more accurate than "plucking out of thin air" wouldn't you think?
Most astronomers work on averages anyway, not guesses.
Telescopes can see the density, light, radiation, gravity, mass, among a lot of other stuff in galaxies, which then can be used to calculate an average of stars. Then going by our own solar system they can work out the probabilities of earth like planets orbiting them, and each one of those planets has a high probability of life, and we know this because, we have life on Earth.
So the probability of life elsewhere in the universe? considering the amount of stars and galaxies we can see (and what we cant), pretty damn high.
The only thing that needs to be proven, is we have life on earth. Now its just a matter of finding life elsewhere.
Probability is only the word they use to help people understand because like i said previously, normal people will never grasp the kind of numbers used.
heh heh so a guy who says Hawkins is an "idiot" and that "Probabilities that scientists have come up with are plucked out of thin air." is right? Please explain how you came to that conclusion
