Is there life outside earth?

Sorry that this is really long, but the first 3 paragraphs contain a short answer and the rest is guess work and unusual ideas.

Some scientists can get overly sentimental over a subject, they are only human, and this sounds like a scientist doing just that. The idea going through this guys head is that humanity is far too special for there to be anything else close to us in the universe.

We have to assume that the only way life can become intelligent is through evolution and the conditions on Earth are the only suitable conditions (this is a pretty big assumption, but we cannot see any other intelligent races so we have to assume that intelligent life needs something similar to the Earth to evolve). If this is true only a tiny portion of planets out there could have intelligent life. Then we do not know how long the average intelligent species survives (there have been several ocasions in our pre-history where the human race was nearely wipped out completely and now we have of weapons of mass destruction).

However the universe is huge and we cannot even tell how common Earth like planets would be among our nearby stars, so I personnally think there are other intelligent species out there.

There are theories that there might be life on Mars and some of the larger moons of Jupiter and Saturn. Besides this, we have only done a little investigation of the other planets in our solar system, there could quite easily be life on these planets that we never knew about, though it seems unlikely that they would be intelligent.

Not only is there the idea might have evolved on other planets, there is even the idea of "Heisenberg Brains" (at least I think that is what they are called). I personally think this is another scientist getting a bit too interested in the idea of meeting ET and coming up with something really daft. This is the idea that a random life form could literally pop into existance for no good reason. In theory it could happen and the creature(s) would be really unusual and interesting, but it is SOOOOO unlikely to happen that I really wouldn't bother trying to find out if there are any of these around the universe.

I don't have all the evidence, so I can't make a fair (believe / don't believe) judgement.

It is possible, but improbable. And if it exists somewhere, the co-incidental possibility of finding life "near" (within a few hundred light years or so) earth is more improbable. That is the bleak prognosis for the life question, let alone intelligent life.

And nope, primitive life is not thought to exist on Mars. The urban legend is because there has been a rock found in Antartica a few years ago, believed to have been hailing from Mars, which a (ever shrinking) minority intially believed might have contained traces of bacterial life. The current debate is whether Mars could have had surface water, warmer temperatures, less rediation, a liquid core and a less hostile athmosphere in the distant past, which, if all true, could have harboured primitive life similar to (but unlike) primitive life forms on earth. Even if that is true, the debate would start whether such life originated independantly from earth.

The point about life on earth, is how utterly implausible it is that life could exist anywhere, even right here. Consider the single cell evolution theory. Ever thought about the single cell aspect of it. That means if the theory is true, (surviving) life on Earth originated exactly ONCE. That is ONCE in 5 billion years. That means life isn't even an inevitable development even if circumstances favour it. That's if the theory is true. The alternatives are equally damming. Everybody agrees that we are all build on the same "template".

Given all the different life forms on land and in the ocean, intelligent life, too, developed exactly ONCE. I don't think we can imagine the uniqueness of it.

You cannot believe that life "probably" exists somewhere else, without throwing maths, statistics, biochemistry and biology out of the window. The universe is big, but in relation to the probability required for life, it is insignifficantly small.

The milky way galaxy has over 100 billion stars in it and there are over 100 billion galaxies in the Universe... That's a lot of potential stars... Some of the galaxies are over 3000 times as large as our own milky way! The problem is that we can see only light waves not planets since the light they reflect is very small. It's almost an impossible prospect that there is not life out there somewhere... The question is whether or not the life has evolved into some sort of intelligent life; when you consider different temperatures, gravity, a huge asteroid 65 million years ago that allowed the development of mammals in lieu of reptiles, it seems unlikely, until you look at the high probabilty presented by the huge # of stars in the universe!

Of course, when you consider something like 650 million light years away... the likeliness of finding something in our lifetime suddenly becomes a difficult proposition...

If there is intelligent life why are the skies silent? Frank Drake, the author of the famous equation which suggests that the galaxy is full of civilizations started SETI over 50 years ago to establish contact. BUT THE SKIES ARE SILENT.

The Fermi Paradox, a quick calculation by the great physicist Enrico Fermi asks "if there are aliens, where are they?? He calculated that any interstellar capable civilization should be able to colonize the entire galaxy in a period of time of 5 to 15 million years. Yet look around, do you see any aliens. Is there an alien under that bush? NO.

There are planets in the cosmos almost beyond number. Some alien fan boys claim that this is proof that aliens exist. Nonsense. Some people take a Cosmos joke about "a waste of space" seriously. Alien fan boys have turned aliens into a article of faith. They've turned it into a religion. And like all religions, they don't have one shred of evidence. Its all FAITH. How pathetic.

One need only accept that the chances of intelligent life developing are so absurdly low that the high number of planets means little. It explains the SETI failure. It explains the Fermi Paradox. I am an agnostic. I am not claiming a god has created us. I am claiming we are just a cosmic fluke.

It's no wonder no one has heard of this professor or the University of East Anglia. If you consider the size and age of the universe, you would have to be an idiot to think that we are the only intelligent life that exists. Although, the chances of them looking like us, breathing oxygen and being carbon based may be small.

I wonder if there is any intelligent life on earth. The way we treat each other and the earth itself it makes me wonder. Perhaps we need to treat our planet like it is not a disposable tissue and a one of a kind place that if we mess this one up there is no place to go. End war on each other and end war on our planet's environment and we may have a chance to survive.

I totally believe there is life (intelligent life) other than on Earth.

Everyone MUST see the National Press Club Meeting that was held in May of 2001. I think everyone needs to know about what's REALLY going on and THEN you can form your opinion.

***** www.disclosureproject.org ***** (watch the video)

Call me crazy if you want but I believe this information may be some of the most important/simply amazing information you will learn. This would especially be GREAT for skeptics!!

The Disclosure Project was founded by Dr. Steven Greer, and to read his stories will leave you with your mouth wide open. "Hidden Truth Forbidden Knowledge" is a must-read.

DLM's reaction is the terrific technological awareness might provide you. "Drake's Equation" is rather an exercising in information the consequence of very low opportunities with huge ranges of envisioned values. figuring out what the consequence certainly is isn't yet interior of our threat, even nevertheless Carl Sagan argued that the billions and billions of planets around stars in billions of galaxies finally leads to a advantageous wager there is different existence available, however the definitely consequence of the learn must be that the uncertainties multiply and the consequence turns into much less and much less specific.

why is it slim lol, theres life on this planet so it would be pretty sad thinking there aint life on another planet or universe out there in space and beyond!! we just need greater tech to explore deeper! there could be another universe deep in space with an identical sun to our own with more people or aliens etc etc

think it through :)

there could be another earth somehere with the same questions being asked!! crazy i know but not unbelievable!

Yes. There's got to be. Maybe not in our Galaxy, but there are billions of them out there... there's got to be a planet out there with extraterrestrial life on.
