http://www.guardian.co.uk/news/blog/2009/aug/17/ufo-mod-files -fyi both the uk and france have made public their ufo files and some of the cases they cant explain -if u click on the link, the first you tube video is a bbc interview with a former uk minister of defense researcher on ufo incidents who is convinced ufo's are real -personally im a cynic but im interested to hear what u guys think
there is way too much space out there to think there is not other life...I also find it shortsided that some scientists think you must have water to have life...as if there are no other possibilities if a human cant think of them
I haven't seen a shred of evidence there is life anywhere outside of earth. The opposite is true, actually. Everything is a gas ball, a frozen wasteland, or a frozen desert. Plus if the odds of life out there are what the believers say they are, a broadcast we sent (any old one, TV or radio) 50 years ago would mean that anyone within 25 light years could have responded by now. And there's a LOT of stars within 25 light years. Not a peep.
We cant even comprehend how tiny we are in the universe. Exploring our galaxy is nothing compared to the vastness out there....
Milky Way is 100,000 light years across. The universe is about 65 billion light years across. But if life on earth is any indication of things, it takes hold and is near impossible to kill off (we've had several near full extinctions, but nothing's killed everything). Why wouldn't there be life within 25 light years? http://www.atlasoftheuniverse.com/nearstar.html
http://www.atlasoftheuniverse.com/50lys.html This is a map of every star within 50 light years visible with the naked eye from Earth. There are 133 stars marked on this map. Most of these stars are very similar to the Sun and it is probable that there are many Earth-like planets around these stars. There are roughly 1400 star systems within this volume of space containing 2000 stars, so this map only shows the brightest 10% of all the star systems Still not a shred of evidence of even a microbe out there.
We don't have enough technology to collect evidences of microbes outside our solar system right now, so this isn't very relevant. We actually found limited evidence that microbial life might have existed or still exist on Mars.
i tend to agree with u but did u watch the interview with the uk ministry of defense official who believes in ufo's? its provided in the link
bingo, why should they care...maybe WE are the ones with crappy technology...do you want to talk all day to a mentally disabled person?

Speeds, I've heard Hawking talk about his belief that life must exist elsewhere. But let me ask you a question. If we're going to play a numbers and probability game to support this belief, then why isn't it also believable that there must be at least one other Steven Hawking (a clone, a literal copy, the same guy) out there?
I do, too. I haven't read the book, just heard about it a bit. There are a lot of variables other than chance that need to be considered. Like the Earth's moon is really big in relationship to the planet, especially compared with all the planets we know about. The moon was a lot closer early on and the tidal forces really stirred things up. It also keeps the planet from wobbling a lot more than it does. We have a magnetic field that protects us from deadly radiation from the sun. An ozone layer to protect us from UV. We have plate tectonics, something I don't think we've found anywhere else to date. It's estimated that 60% of all stars are binary (two or more stars) systems. I have no reason to expect those to support planets with life. I'm not factoring into that 60% that we have no reason to expect life to exist around any star unlike our own. If the big bang theory is correct, we can clearly expect that stars close to us (like within the 25 and 50 light year radius I mentioned earlier) are the same age as us. Something 50 light years away is less than 50 years older/younger than us due to the fabric of spacetime stretching (like 1/2, so 50 light years would be only 25 real years difference). If Evolution is universal, and no reason to expect it isn't, then any life there should have basically evolved starting at the same time as ours. Then there's the obvious: http://en.wikipedia.org/wiki/Fermi_paradox
