Your opinion Do you believe in life on other planets?

Definitely in the case of simple life forms, if only from a simple mathematical perspective. Intelligent life seems a bit more chancy, but it seems still probable. Whether or not we would ever contact that life seems a very distant possibility indeed because of the obstacles involved. First is technical: the difficulty in detecting the other civilization because of the differences in level and types of technology (for example, a civilization here on Earth which uses only radio waves to communicate would be oblivious to microwave cell phone messages). Then the tremendous distances over which a message or spacecraft would have to travel must be addressed. Even after surpassing these technical issues are the motivational factors in that there is a good possibility that the nearby civilizations would have no interest in contacting us either because they are too advanced or just lack the motivation for interestellar discourse. It would be unrealistically arrogant of us to assume that all life forms would share the same interest in studying  sociological interactions in simpler organisms.

The laws of probability makes it a yes to your question.  We are not alone.  In fact earth is just a speck in our own galaxy.  Our galaxy is just one of many galaxies.  Yes it would be amazing to find other beings....provided they were friendly...LOL

lol yes...well something like it. I believe that God made other things than humans. Alright now think about it . This is just one planet, which is quite small. THere is a whole solar system out there. The only reason why we get a full population of life is because most thngs adapt and their living conditions are here. Tell me why not there wouldnt be other life other than on this earth. Alright not convincved? Well think about this. Why would there be so many other planets in this solar system that we can't live in...what will actually be a point. I think that this alien thing isnt as as exaggerated as humans have cracked it up to be but dont doubt that there isnt some creature not naturally adapted to earth. This is our planet, we can't live on any other one; hence the word OUR PLANET and WE CANT LIVE ON ANY OTHER lol. I havent seen one but i dont doubt theres life that isnt adapted to this earth.

Who said most of us believe in aliens?  If by "aliens" you mean life existing outside of Earth, then I guess I would speculate that aliens exist.  If you have the impression that aliens are little green men that visit Earth in UFOs and use probes, then that is just ridiculous.  Considering the billions of stars in each of the trillions of galaxies that exist in our solar system, it seems logical to assume that at least one other planet in one other solar system has some form of life, even if it is only similar to bacteria.  There is no proof, much in the same way that you cannot "prove" that aliens *don't* exist.

i believe they exist, only because I believe that the universe doesn't end meaning that mathematically on some other planet, it maybe one out of the speed of light, but it is possible beacuse theere are millions apon billions of other galaxcies all with many other planets and chances of producing life\n\nhowever with that being said the closest galaxies have aready been examined and concluded impossible to produce life as the planets of the other systems are way too harsh to support life, let alone intellegent life, not too mention those galaxies are light years away, so any one who beleives in alein encounters are bogies.

I think you were watching a sci-fi show, maybe artist's conceptions of planets in other systems. We can confirm that the other planets exist by watching for gravitational anomolies but our tech isn't up to the task.

alot a people say that there are lives on other planets bout think about this, if they were life on other planets wouldn't they have been in contact with us or we would have picked up their radio signals if they were that advance in technology and we would have gotten visitors very often.\n\ni read in a book, the man said if there are life on other planets that means they would be as advanced as us humans, more advance than us, or still in there type of stone age. \n\nif they are as advanced as us, we would have been in contact with them(as i said earlier). If they were more advanced than us(as alot of people say) they would be visiting our earth for holidays and coming to see our civilizations. and if they are still in the stone age, we would be able to pick up they communications.\n\nit is true that bacteria was found but no from of intelligent life is out there. remember in Genesis it was said we are created a lil lower than angels, crowned with glory and honor. We are made to have dominion over all other life, so tell me this if God made us like that then why would he make something that would be better than us? We were made perfect, he actually used his hands to formed us to show us how special we are to Him, all the other animals were bought from Him talking.

no, but it would be very stupid to assume that Earth is the only planet that can sustain and contains life.  the universe is gigantic.  i don't think any human can truly grasp how vast the universe is.

I think they will be on some other planet.
270604
Yes, I think it is possible.  We live in such a great universe and there is probably another life form out there.

Yes, it is entirely possible that there could be planets in other galaxies with life on them. There is nothing preventing the same conditions on our world being found on another world. It doesn't matter what people think about "aliens visiting our planet" or whether we can know about life out there. It definitely is possible.\n\nAs for the comment from Iamtheweasel: The bible doesn't say that you exist, but there you are! I don't mean to be rude, but does the Bible really have to say everything explicitly for it to be true, or even probable? It absolutely does not contradict that there is life on other worlds. From a fellow Christian, please don't be so closed-minded, especially by using a "No true Scotsman" fallacy of definition to define a Christian as one who doesn't think it's probable that there is life on other worlds.

Chances are, yes.\n\n90% of all solar systems are not in a circle so they can not support life.  Of the 10% that are left what are the odds that another planet is moving around a sun where it's not to hot or too cold. Even in our own little solar system there is only one.\n\nSo, if there is life elsewhere, we will never meet them.

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.

No I believe there is other life out there somewhere. The universe is huge so how could we be the only planet to have life?
765259
No, there is almost certainly life within the Universe besides Earth, and there is certainly life within the Milky way besides earth.

No they live on different planets

There are too many other planets in the universe to say that ours is the only one with intelligent life on it! That's human arrogance to say this one planet is the only one with intelligent life. Since we haven't meet any,then their aren't any! Is what most people believe,but I think their is! Everyday we are finding new forms of life right here on our own earth that we didn't now was here,til we found it. Space is so vast, the universe is endless and other species from other worlds probably face the same challenges that we do in space exploration. They haven't discovered how to travel through space and such great distants just as we haven't. Or have they? Remember The Thing! Who knows what could be frozen under the Artic and how long it's been there! Also, I believe that their are species much stronger than us, with the power to inslave us or put us on the food chain. I know this is far out,but think about it...we as humans eat every other animal on the planet cause were the strongest! Now if a stronger species than man took over the earth,who knows man could be on the menu!!!
