who thinks there is life out there?

I think there is life out there.

I believe there is life in our solar system (othert than this planet). I believe three places for us to check out further are:

titan

io and

mars

These three really interest me because they have all shown signs of water, especially titan!

Thats only my opinion, it would be interesting to see what other people think!

possibly! I think there are some out there in the universe. I mean, the possibilities are endless!

they are,.. we can;t even see a fraction of the universe, let alone the whole thing, whats beyond what we can see?

but is there any intelligent life

I believe they will find that life is very tenacious, and instead of needing just the right conditions, is very adaptable, and will take hold in places that would surprise us. Look at viruses....they don't even meet all the definitions of life, yet have outwitted man for centuries. The life around vents in the oceans depths is thriving in what would be considered very inhospitable conditions.

I agree that life is tenacious and I think there must be countless places in our galaxy where life could survive. An important question I think is how likely it is that life arises in the first place. Also, how common are the conditions that will likely give birth to life. These may be rarer than the conditions that existing life is able to adapt to.

For anyone interested, here's Carl Sagan on the Drake Equation.

Seems very likely. In the words of the hitchhiker's guide to the galaxy "the universe is big, real big". It is now becoming clear that planets are very common, and many of them will have conditions conducive to organic life. The question of how much of a fluke it is for life to appear given appropriate chemical and thermal environment is a very tough question, probably best answered by empirical data. The story of how life appeared on Earth from the chemicals produced by lightning in an anaerobic atmosphere is still very hazy.

Elroch, I completely agree!

BTW, hitchikers guide to the galaxy is a great movie, but and even better book!!

there is! but not in reach of us!!!but there is a fine line on what in fact you think is life. right?

right chriz01!

I remember reading (not so long ago infact) that they were shining a light beam onto the stellular system m13. The light pattern was showing human life.

This is something to do with it. http://www.adrianberry.net/art49.htm .

got it! http://www.bibliotecapleyades.net/imagenes_circultivos/chilbolton06_04.gif . The picture on the left is what we are sending to the m13. IT represents humans and DNA. If you want more information, type in "binary code sent to m13" into google!!

When you look at the sheer number of galaxies, stars, and potential planets in the universe, the chances for life, and intelligent life are very good.

Now, if you want to consider the possibility that we are being visited by extra-terrestrial life, I would say it makes no sense to expend the energy required to travel here and not make yourself known.  That is why I think that there are either no-such-thing as UFO's, or that they are a different type of phenomena.

Of course the big problem with sending out messages like the one sent to M13 is that it could so easily be interpreted as a menu. 

lol!

there is life out there!!!!  it migth be on mintaka star hehe

If there is intelligent life out there, maybe they could give us a hand. I believe we are all searching ardently for it down here.

In regards to the Drake Equation, I think 10 civilizations is closer to 1,000,000 in the galaxy.  Life is probably abundant relative to intelligent life, IMO.

On the topic of UFOs, I believe the physics precludes any real ETs visiting earth.  Given the light year distance and the fact it is against the laws of physics in our universe for any object w/ mass to travel greater than the speed of light.  The logistics (fuel and food) alone make this a daunting journey. 

Actually, depending on how you define life ... say we believe there is life if something is alive ... then life may be quite abundant but not as we know it or expect it.
From the Drake equation we should be able to see heaps of signs of life from the Andromeda Galaxy alone. However we do not. It has been long enough in our search to have seen at least something but the Universe is ominously quiet. Life, even intelligent life, may be abundant, but it is incredibly precious. We may be the only life form of our own particular bent and abilities. That may be true of all life whether it meets our rather restrictive definition of intelligence or not. It appears that all life is far more precious than we can imagine.

Suppose we assume that human beings are the first technological creatures to evolve on Earth. Then it has taken about 4.7 billion years to get from a viable planet to this level, about half of that time since life appeared. This technological state has so far lasted less than a millionth of that time (depending on where you draw the line). The time it has taken is a large fraction of the expected lifetime of the Earth. There is no particular event that is believed to have caused the evolution of us from animals which have no thoughts of communicating with Alpha Centauri, and it can be taken to be an essentially random event.

It is entirely possible that the probability of a world evolving technological beings in less than 10 billion years is very, very small indeed and that Earth is unique or very rare in having done so. The difference between us evolving at 4.7 billion years and not at all before the Earth gets vapourised is a very slight one.

Hence be suspicious of all calculations which estimate how common life is, and how common intelligent life is, based on no adequate theoretical model and one (biased) empirical example (unless you count the lack of evidence of life on other planets in our solar system, and the lack of communication from further worlds as being negative empirical evidence).
