Is there life in other planets besides earth?

adding to snagelfritz, there could bve life in a gas giant.  They would float on blimps, and be hunted by gliding organisms with sharp claws to tear right through them.  Several forms of life could exist in the solar system, like also on titan, there could have possibly been life, giving the fact that the atmosphere is made up of the same elements as ours!

A recent scientific study estimates that there are AT LEAST 70-sextillion stars in the universe, one of which is of course are own sun. The odds AGAINST none of those other stars having planets occupied by sentient life are astronomical (pun intended). Undoubtedly of all the life forms that exist in the universe some are technologically at the same level as we are, while others are at least several thousand years ahead of us. Still others might be where we were 3-million years ago---just down from the trees. Certainly, any alien life with any intelligence at all must wonder if there are other life forms somewhere other than their own world.

life on other planet would not mean they should be all humans. don't forget on our little planet there are 1000s of different living creatures, they are not all human. therefor there might be life on other planets in different shapes and different creatures, that would not mean there was some other God who created them.\nThe Bible says god created the heavens and earth. it doesn't say if God created or didn't create any creature elsewhere.\nthe bible was sent to us earthly human to learn about God and how to worship Him. There was no point to intriduce other worlds to the ancient humans because of their lack of understanding.\nour understanding of how to interpret the bible changes through time and history.\nThe early church thought of science as anti-religion. and they thought the earth is the center of the universe, even though the bible doesn't say that, it was implied that God will create the earth and give it so much attention only to make it the center of everything. But as we learn more things about the universe we read the bible and see there is nothing in the bible that contradict it. so if one day we discovered life some other place, there is nothing in the bible that says that should or could not happen. it is only our understanding now that assumes God created only living creatues on earth..

I doubt that there is life there or elsewhere in the universe. Yes there is ice in outer space and probably on portions of planets which means there probably was water out there at one time. However there are too many variables missing for there to be life as we know it. Believing that there are physical life forms other than as we have here on Earth is just speculation. The more space is explored, the more we know that Earth is uniquely made. If you get a chance see the dvd, "The Privileged Planet".

No body know for certain. However, the universe is so vast, with so many celestial bodies that it seems rather improbable if the only place in the whole mutiverse that harbors life is planet Earth.

Definitely.  Even if its just some microbes out in space, just the sheer number of planets and stars etc I would think there would have to be other life out there!

Well, the bible doesn't say anything about life on other planets.  It doesn't say that there isn't life on other planets - it just doesn't give us any directive about what that life is like or what our relation to it would be.\n\nThe bible is silent on the topic.\n\nInterestingly, C.S. Lewis, a famous Christian author, once wrote a science fiction trilogy about life on other planets.  The books in the series are:  Out of the Silent Planet, Perelandra, and That Hideous Strength\n\nC.S. Lewis is my favorite author and that was a great series as I am also a huge Sci-fi fan!

not in our solar system. \nBut you also have to remember that even if there is life on other planets, we are assuming that they are as advance as we are or more. Could it be that maybe they are in a pre-industrial era and have no means of space exploration?

if ur asking if we, as humans, can be sure the no one else exists on the other planets? then no..no one can be so sure, but the facts gathered about the other planets, such as chemicals in the air, etc... can tell something about the planets..

i think there is life on other planets but they probably won't look like the ones in movies and if if there are why would they want to invade  this tiny spek of dust in the vast universe?

Not yet. Organic molecules, considered as precursors to basic life forms, have been found throughout the Universe (mostly in comets, interstellar gas and dust). Experiments show that some bacteria and archaea can survive the severity of outer space. So it's quite possible that we find living organisms in the future, most probably on other planets.

I am almost 100% certain that life DOES exist on other planets, and may be in completely unfathomable ways, that we could not begin tio understand.\n\nIt us very interesting that the prospects of life having once existed on Mars are become more likely, due to the significant discovery that water once was in abundance there.\n\nThe trouble with finding life in other solar systems is that the distances are just too great. Even radio waves take 4 years to reach the nearest star from the Sun, then you need 4 years for the reply. The majority of stars are MILLIONS of light years away. so EVEN if there are a Billion planets with intelligent life there is no way of being in contact.\n\nBUT I do hope I will find out that DEFINITE life has been proved to exist before I die.\n\nI find this a fascinating subject.

The short answer is: \n- - - - - - - - - - - \n\nYes I think it is fairly likely that there is life someplace outside our solar system. I have written a short historical survey, and then summarized some of the reasons behind my answer. They boil down to 2 points:\n\n1. The universe is a big place\n2. Life seems to be pretty common here on earth and start pretty easily. \n\nThe Long answer:\n- - - - - - - - - - - \n\nA. History\n- - - - - - - \n\nThis is a question that people have asked for a long time. The Greek philospher Epicurius (341–270 B.C) speculated that there were an infinite number of other planets like earth, with life on them, in the universe:\n\n“There are infinite worlds both like and unlike this world of ours...We must believe that in all worlds there are living creatures and planets and other things we see in this world.” Epicurius (c. 300 B.C)\n\nThe Dominican Monk and philospher Giodarno Bruno conjected in his 1584 work, "On the Infinite Universe and Worlds", that there were an infinite number of other worlds with intelligent life on them. He refused to recant this and other controversial beliefs, and was burned at the stake during the Inquisition for this. \n\nThe famous physicist Enrico Fermi formulated the Fermi Paradox (sometimes known as the Fermi Principle by skeptics), which states that if advanced intelligent life was widespread in the universe, we would have evidence of it already. Since we do not have good evidence, where are they? \n\nThis was later addressed by Frank Drake with his Drake equation (aka the Sagan equation or the Green Bank equation) for trying to estimate the probability of using coming in contact with an advanced extraterrestrial civilization. \n\nBoth a modification of the Drake Equation and the analyses associated with the Fermi Paradox can be used to try to estimate the likelihood of there being life beyond our solar system (the interested reader is directed to the references). Basically, depending on what is assumed for a number of parameters, it appears either quite likely that there is life outside the solar system, or quite unlikely. However, at least one has a better handle on what the quantitative factors are that go into estimating this probability by this kind of investigation. \n\n\nB. Reasoning Behind my Opinion\n- - - - - - - - - - - - - - - - - - - - -\n\n\nMy own opinion, after having read this material and some of the links contained, is that it is quite possible that life exists beyond our solar system, or even possibly does or has in other places in our solar system than earth. \n\nFirst, consider the very large number of stars even in our own galaxy (200-400 billion) and the large number of visible galaxies. This leads to about 7x10^22 stars in the visible universe (according to  Dr Simon Driver of ANU). This is more than 10 times the number of grains of sand on earth. This is 100 billion times more than the number of letters in the 14 million books in the Library of Congress. If this is coupled with the seeming presence of a large number of exoplanets around these stars (170 found as of the end of 2005, and we have barely started looking), then this translates into a HUGE number of planets. With this extremely large number of potential planets, there are bound to be some like earth. \n\nLife seems to thrive readily, since life started soon after the earth cooled and existing in environments that we can barely imagine, like miles underground, or near deep ocean vents, or under the Antarctic ice. It has been well known for years that there are amino acids, the building blocks of life on meteors in space. Scientists have also created amino acids in environments similar to deep space environments (see reference). The Miller-Urey experiments in the 1950s were also able to readily create amino acids in environments meant to duplicate a primordial earth environment (reference below). \n\nWith the evidence that there are probably many planets with eart

No one has yet shown that there is any life beyond that on Earth. \n\nAs far as life in general is concerned I am reasonably sure that there is life on other worlds and there are currently a couple of space missions in development that may find earth-like planets and even find signs of life on those planets in the next few decades.\n\nWhether there is intelligent life out there is more debatable.\n\nConsider that in 4.5 Billion years the Earth has only produced one technological intelligent species. This species has only really been able to consider possibly contacting or being contacted by intelligent beings from another world for the past 50 years. In that time we have just about managed to avoid nuclear annihilation, so far, and are currently well on the way to destroying the Earths eco-system.\n\nIf intelligent life is anything like Homo Sapiens then it will probably not last more than a few hundred years at a level where it is technically able to contact others.\n\nGiven that, it is extremely unlikely that two intelligent species will evolve close enough together to contact each other in the short time frame that they are able to do so.\n\nSo while there may be intelligent life elsewher in the universe I doubt we will ever find it.

We are one of many planets surrounding a star at the edge of a Galaxy which contains billions of other stars.  There are many other galaxies in the universe with about the same amount of stars and planets.  I think that we would be naive to think life does not exist anywhere else.  I don't know if we will ever be able to travel the distances required to find out.  Technology will have to develop a considerable amount for that.  But, considering what we have accomplished in the last 100 years, we may do it.  Maybe not in my lifetime, but in yours or your children's.
