do i believe that life exists elsewhere? meh, i'm not sure. but to claim that the odds are in favor of life existing elsewhere is silly when the chances of life existing on our own planet is so slim.
If he calculated the odds as greater than all of the atoms in the universe, and yet humans are here, his estimate appears severly flawed and invalid.
My personal guess is there are perhaps dozens of planets with advanced life, in our galaxy alone. It could be in the hundreds of thousands, millions even, considering the size of the entire universe.
thats what the odds are...based on anthropic constants, for life to exist without intervention.
though your train of logic is interesting. preconsieved belief>confronted with data>life exists, so data must be wrong>preconsieved belief holds.
nothing really wrong with it, though either you misread, didn't read the link, or tossed out the possibility of an overarching god figure.
To my logic, if the hypothetical aliens have mastered intergalactic travel etc, would they really be some barbaric morons? I think we're reflecting our own idiocy to other possible species here.

as much as i love hawking, his logic is flawed, he has underestemated the odds. there are things called "anthropic constants". basically, precise and narrowly defined variables that must be exact for life to exist.

It's not actually Hawkings' idea:
Drake Equation
The question is more like: if it's so probable that other life exists, why haven't they contacted us? Or maybe they have, who knows.

That's a pretty narrow-minded way of thinking about it. This is the Universe we're talking about. We don't know how many planets there are, and we don't even understand how large the Universe is. To even mathematically calculate this with so much missing information (unless you make stupid assumptions, like the guy you quoted did) would make it incredibly inaccurate. There are so many unknowns -- we know very little. I am going to assume (like the guy you quoted) that life is very abundant in the Universe. I don't even see how it couldn't be. The math above is just full of a bunch of guesses.
Also, I tend to think there are more than 10^22 planets in the Universe. A lot more.
Peace.
One Love.

Like I said it's a no brainer that extraterrestrials exist based on recent scientific discoveries.
Similarly, Lord Rees, the astronomer royal, warned in a lecture earlier this year that aliens might prove to be beyond human understanding.
“I suspect there could be life and intelligence out there in forms we can’t conceive,” he said. “Just as a chimpanzee can’t understand quantum theory, it could be there are aspects of reality that are beyond the capacity of our brains.”
