Does Life Exist Elsewhere In The Universe?

With an average of 5 planets per star (that's my conservative guess) half a trillion stars in our solar system, and an estimated 100 billion (KNOWN!) solar systems, we have 2.5*10^23 planets in the universe.  This number will definitely continue to grow as our telescope technology improves.   I would say that the odds of NONE being habitable are VERY small.  It's kind of like trying to roll a dice a hundred times without hitting a '1.'  You have to hit something eventually!  Especially different types of life like microorganisms, which can survive in fierce environments.  With so many planets, advanced life is very probable elsewhere.  Problem is, the light emitted from Earth takes billions of light years to reach the further planets, so if they somehow saw us through a telescope, that activity will have been from billions of years ago.  Life will be long since gone by that time.

Progress will be difficult, considering that the closest habitable planet is 25 lightyears away.  If we can manage to send colonizers, we will probably never speak to them again, since any light-based communication will take 25 years to reach us.  We will have to find a way to break the universal speed limit which is the speed of light if we want to overcome this obstacle.  Still yet, relativity will hold for those who travel and we will age relatively faster and will be dead sooner than them.  Once again, a problem for communication.

Of course they might figure out how to analyze spectral samples for signs of life (I remember hearing they did something like this recently), which would not require us to physically go there.  But I do hope we find a way to physically go there!

My Answer Is also Yes I believe we would be extremely arogant and nieve to say that we are the only intellegent life in the universe I have done lots of research and found many interesing things on the web. However its all written by humans who have a knack for lying so the only real answer remains to be seen and yes I am 33 and do believe proof will be found in my lifetime.

Yes.I would like to think we aren't the only life form in the universe. It's a big place and  scientists and astronomers still have a long way to go if they're going to declare every single planet uninhabited. Just wondering if there are some other beings thinking the same thing about us out there somewhere.

Of course,scientists have found evidence on Mars.Don't think aliens are just coming around to look,progress has been made already.All you have to do is look up in the sky,someone just might be looking at us.

This universe is too huge for us humans alone, and there may be many other life forms throughout the universe. But it all depends on how we define the life forms. We believe on carbon based oxigen breathing life forms based on water. But there can be other forms of life. If they come to us, they has to be surely intelligent than us. When they send a ship, while it is travelling, they would have developed thousand times more.
I say, Surely!

Yes, life also exist in some other planet.Man can't imagine.God has created this universe we can't imagine how much living things exist in this universe.We can think according to our mind but God knows the truth.Science is searching to find the secrets.So it takes time to find out by man.

Other than the stray parasite, bacteria and amoeba, I'd say the chances are slim as far as finding other humanoids or their variants.  I'd personally like to know why is it that every photo taken of a UFO is always grainy and never an alien waving out of the window!  HA

Yes!Why not believe? You can not deny what you do not know. I can see people here continue exploring.

If space is infinite, then logic suggests that there must be life out there.

Life can exist else where in the universe,because we know that to be live any thing there should be such atmosphere or ingredent needed for life if some where except earth these are all available then the life can also be available there.

Yes not in space ,it is my belief that there is a world after death it exists now that is evil good, demons angels and it will come to a head someday looks like soon.

Space knowledge has made many historical  advances in my life time and everyone worries about little green men. I say it will give us one more color to  learn to accept  and  see if we can control how they feel and think. After all are we not the perfect race?I hope there are little green men and they obviously are very intelligent because they never stay very long to visit.I believe it is possible after all look how long the legends of the mini horses floated through the Indians and every one thought they were crazy made up fables-they really did exist.

Actually the word ''LIFE'' implies to the fact the what we feel and what we see. well!! the Almighty Gods knows better but nevertheless what I think is that there do exists life there on other planets but we can't see them, similarly as they can't see us.

Moreover, the universe is not never-ending; it is spectacularly huge (concerning 80 billion light years transversely, and increasing earlier than the speed of light) but it nonetheless has a limited dimension.

Though, judge by the beginning survey discovery planets, it seem rational to presume that there is almost certainly living inside and merely 100 light-years of world. The Kepler breathing space get smaller, due to be launch in a pair of years, should have some ultimate information on that inside a decade.

That creature said, there is NO cause to presume, now since confirmation of life is establish, that there will be clever strange variety in that radius. I remain intensely cynical that there will be getting in touch with an intellectual Martian contest in the natural life of anybody living wage these days. That's because the chances are not now stretched out by the unintelligible immensity of breathing space, but as well by the astonishing immensity of time.

Human contain simply been able of radio communiqué (still only in code) for 100 years; the universe is about 14,000,000,000 years older and our planet's 4,300,000,000 years older. That imply there is no cause to presume there should be an unfamiliar society at a companionable technical stage within a rational distance.

Yes, I thought of that a lot like if there're other galaxies with an earth and human that only think of peace there.

Yes, I believe it is incredibly possible that life exists on other planets light-years away.

Given the vast size of space, and the insane number of planets and stars, you would have to be an idiot to think we are the only life form. The real question is how many, and what stage of development. I feel confident that we have been visited by visitors from far, far away, and possibly contacted at some time during our evolution.

The probable is that they would be far, and I mean way way far more advanced than we are, they probably wouldn't even consider us worth communicating with. To date, I don't think we are even able to see a planet the size of ours circling another sun, We are trying to detect them by the change in light as they cross the path between their sun and us.

Well guess what, if they were watching us like that, it would only happen once a year. So if they found us, it would be like us finding a tadpole on Mars. We might study it, but we probably wouldn't try to communicate with it.

I have to believe that with so many planets in our universe, life must exist somewhere besides earth.  It may not be life as we know it, but the odds tell me that somewhere "out there", other civilizations are asking themselves if we exist.  

Whether or not there are more advanced beings in the universe, I won't venture to say.  There may be life that is less advanced, more advanced or even at our level.  It is interesting to speculate about it.  

I don't expect more progress in finding other civilizations during my lifetime, because as yet, humans don't have the capability to travel the distances that would have to be covered in order to reach planets outside of our solar system.  Scientists are just now working on the challenges that would be faced in order to get us to Mars.  It's a very tantalizing objective, but there are so many variables to be taken into consideration that it will probably be many years before all those problems can be solved.  Even so, the prospect is so exciting.

YESSS!!!!!!!!!!!!!!!!!! Of course there is life. God exists and then think about how likely it is that there are aliens. You think we made that up on our own. Some of them are even zapping cows' body parts out of them. It's a big deal on farms out west in the US. BIG ISSUE

Yes, imagine the odds.  There may be a billion galaxies out in space, in those galaxies three may be millions of plants. Even if .00001%of those plants have life on them there are at least 1,000,000 planets with life on them. Whether or not that life is intelligent is besides the point.

It would be extremely ignorant not to believe there isn't any intelligent life form amongst.... Well for all we know enlessness of space.

Out of all the other planets there MUST be a habitat able to survive on.

Judging by the size of the universe, there has to be 1 planet that life can survive on.

I think so, because if you believe in God, why would he create this HUGE universe, with life only on one tiny planet?

As for up or down man has looked there's life! Even in zero or dead space there is something. Do you see red or green lights?

Yes, i believe so because of ufos.
