The biggest hurdle in people's thinking is the assumption that conditions/environment has to be similar to that of our own solar system/planet for there to be potential life. There's no doubt in my mind alien lifeforms exist, in fact its highly probable they exist in our own solar system. (moon of Mars, Europa,...)
I actually agree with you Doppel!
I always hate when I have to sit there and have someone of intelligence tell me that "the conditions are not right for life to exist on this planet/place." I just want to smack them upside their head.
I think there is.
No proof, but I can't let myself be so ignorant and full of myself to say that we, along with the animals, are the only living creatures.
well... the probabilitys for inteligent life forms to exist anywhere in the universe are far smaller than the probability for a wave to make a sand castle in the beach... yet we are here...
also depends on what do u call life... for instante if u say a living being is that who perform the basic life functions then fire should be consider alive (life function being born, nurture, grow, reproduce and die)
i don't know if beliving or not, but i certainly hope so...
There are an estimated 100 billion galaxies in the observable universe. In each of those galaxies there are anywhere from 10 million to 1 trillion stars. So even if we assumed that every galaxy had the minimum number of stars in it, that'd be 10 million x 100 billion stars that might provide the right conditions for orbiting planets to sustain life. There's this thing called the "Drake Equation" (wiki it), that attempts to factor in all the variables and arrive at a final number of planets that would host intelligent life. The equation puts the number at about 10,000 planets.
Also, there have been experiments in which scientists simulated the atmosphere that must have existed before life evolved on this planet, then they ran electrical currents through it to simulate the lightning that would have existed in the atmosphere. The result was that in a very short time, the chemical compounds that constitute the basis of earth's biological life began to form. Point being, if the conditions are right, life begins to form pretty easily.
Plus, there was that meteorite they discovered that look like it had fossilized microbial life in it.
And in addition to all that, some scientists say that ammonia-based life also seems possible. (Humans are carbon-based; this is basically the "alien life doesn't necessarily need an earth-like environment" argument.)
So, all in all, it doesn't seem too far-fetched. However, we may be disappointed at the kind of alien life that probably exists. It may just be bacteria or something (but even bacteria, compared to all the dust and gas that makes up most of the matter in the universe, is extremely complex and pretty amazing). But who knows?
There was also another article... a giant gaseous cloud filled with the precursors to life and lots of organic chemicals... in space. I cant find that one though

Although it's all just speculation. Put just one of the factors to 0 and you end up with zero planets except for ours.

Although we have never formed actual life yet, which is what opponents keep pointing out.

Well the only thing that really needs to be present for life is water. (as far as we know) At least some form of life.
And given that oxygen is the third msot abundant element in the Universe, there's certainly no shortage of material to make water from.

I'm certain we are not alone, everything we know about life says life is very robust. UFO Bob, I mention above worked out at the site in area 51. We have no lack of people around Vegas with security clearance, they definitely do some heavy stuff out at China Lake. There are untagged non-commercial 737's that take off from Vegas and have no known flight plans, I have seen them.
Of those I have met I've never gotten one to spill what they know, they can't of course, but except to say to me there are some things you should be glad you don't know. They do say there is serious technology getting done in hidden places. These people don't get to talk about what they do, they can't give even their friends a heads up of where they will be except minutes before they do it, even simple things like getting picked up to go out.
You get a call and hear pick me up at such and such a place in 20 minutes, and that is all the warning you get. Then you don't even get to talk about what they do, you just go do friend things and hang with them until they have to leave and then you drop them off at wherever they need to be dropped off at. Not the kind of life I would want to have, but they get paid well for that security clearance.
I believe that the earth is in such a privilaged position in the universe that for life to exist on anoter planet, it have to be in an entirley different universe.
P.S. if u dont know, the earth is in the exact center of the universe. Scientists know this because every other galaxy is travling away from us.
BTW scientists never found 'fossile' of bacteria on mars, it just looked like it could be, they never concluded that is was or wasnt.
Also scientists never created life in a labrotory. They mearly created the phosphilipiteds that make up the cell membrane or 'sac' thats hold the cell together. However they didnt even create that because the cell is made of entirley left-handed phosphilipides, and every biologist knows that, and that whener u make thoughs, there is always 50% left handed and 50% right handed.

The Milky Way is moving like all known galaxies are
Milky Way moving away from void
Astronomers have discovered that the Milky Way and neighboring galaxies are being pushed from the Local Void at 600,000 mph, meaning the void must be very large and very empty. NASA / WMAP Science Team http://www.astronomy.com/asy/default.aspx?c=a&id=5669
X-rays Reveal What Makes the Milky Way Move
A new survey by University of Hawaii astronomers has found that, in a tug-of-war of cosmic proportions, our Milky Way galaxy is being pulled toward the largest concentration of matter in the observable Universe. This finding is being presented today by UH graduate student Dale D. Kocevski and collaborators at the American Astronomical Society meeting held in Washington, D.C. http://www.ifa.hawaii.edu/info/press-releases/kocevski-1-06/
I know this is a weird question, but does anyone have any personal experience with aliens? Or at least think they may have?
I haven't, I have just heard some crazy stories from people before!
When I lived in Monterey (aaaah now there is a place to move back to) I knew a fisherman who swore up and down his boat had a close encounter, he said it got within 50' of the boat. He described a huge saucer like object with a number of lights on it that darted around his boat at insane speeds, and then hovered just above it for almost 20 minutes. He said it made no noise at all and eventually took off like a bat out of hell straight up into the sky.
This guy was a commercial fisherman, he never came across as being egotistical or needing to be in the limelight. Nor did he come across as someone who needed to tell people fantastic stories or anything like that, pretty down to earth person. I took him seriously.
P.S. if u dont know, the earth is in the exact center of the universe. Scientists know this because every other galaxy is travling away from us.
that's wrong... is not that every other galaxy is moving away from earth, it's that every galaxy is moving away from every other galaxy, that's why they say the universe is expanding... like dot s on a baloon when u blow it...
I guess I do believe in them. There are so many many videos of them. Many are fake, but some are too good to be fake. I saw one video recently which seemed to be real.
So yes, I think there is alien life, but I'm not saying it has to be advanced. BTW, they did found fossils of bacterias on mars. And also something that was a ocean at a certain point. (There still is water on mars, because there is ice lol.)
There is life, 100% sure and we are close of proving it. But it's probably very primitive.
There's a difference bewteen finding life, and finding chemical compounts which we know life can create.
There is evidence that life may have existed on Mars, as scientists have found plently of elements and compounds from rocks that we know only life creates on Earth. However, Mars has a radically different atmosphere, making is much more susceptible to cosmic radiation, meaning we don't know if those compounts could have been created in some other way. There are no actual fossils found from Mars soil.

Yes, every galaxy in the Universe is practically moving away from us. BUT, that is how it would look on every planet in the whole Universe. If there's life out there, they will see the exact same thing, that everything is moving away.
This is because space is expanding. Matter, which is present in space, just just moving along with it. Think of the ballong. As it increases in size, any one point of the baloon will get further and further away from every other spot of the balloon, regardless of where it is positioned.

Perhaps when we die, we reincarnate on another Earth planet millions of light years away. But that's for another thread.
For whoever said it: No, the Earth is not in the center of the galaxy. Do you live in the 16th century?
And most likely, we've already found some form of extra-terrestrial life. Probably not in the form of intelligent humanoids, but in bacterial or other forms. Even if we haven't though, I'd say with a lot of certainty that it's out there.
But damn, just imagine what the discovery of extra-terrestrials would do to society. Religion would get rocked.
"In July 2003, scientists at a meeting of the International Astronomical Union in Australia announced their latest estimate of the number of stars in the Universe - 70 sextillion. That is 7 followed by a mind-boggling 22 zeros."
"The new estimate means that the number of stars in the visible Universe is larger - quite a bit larger, actually - than the total number of all the grains of sand on all the beaches on Earth. And this estimate is almost certainly way too small."
"Assuming, for a moment, that the kinds of places that life likes tend to be smallish rocky planets like our own (a big assumption, and one oft-criticized, but more on that later) orbiting medium-sized stable stars in well behaved solar systems, we are still left with an awful lot of cosmic real estate. All the grains of sand in all the beaches in Florida, say. Or Crete"

there are no fossils on martian soil yes... but thats mostly because we have explored almost nothing... mars is more susceptible to cosmic events and stuff but part of the reason scientists believe life might have ceased on mars is due to the fact that the magnetic field around mars is gone but is still existant on earth... and with each passing day, there is less and less of a chance that well ever find anything because everything is moving away at a mind boggling rate but there is an infiniate number of stars with an equally infinate number of planets orbiting them... this creates in infiniate number of possibilities for life to pop up on a planet...

So really, look at all the stars in the sky, assume each star has at least 3 planets and then tell yourself there is no water on all of them.
Then there is also the possibility alien life forms may not need anything that we need such as water, oxygen, climate.
There is also sweet sweet sugar in space
