If there is life on earth, is there life like ours in other universes?

yes.  Here is a post of mine with the info on it about life outside our planet, maybe even in our solar system.  Be aware:  Most planets we found are "hot jupiturs", which are jupitur sized gas giants with temperatutres about 1300F at average.  \n\nThere is a possibility.\n\nI have done PLENTY of research in astronomy. I just am so into it. Anyway, I beleive yes, and my reasons:\n\nEarth itself seems perfect. Perfect climate, actaul liquid water, etc. But did you know animals (and I mean animals, not bacteria) could adapt over time to certain places? For instance, In Jupitur, there might be life. The appearence: Most planets are gas giants, and they need to be able to withstand a good amount of temperature (We are alomst guarenteed the only solar system with rocky planets and temperatures colder than 1300F on average). This would be the perfect place for, as the books described as, Floaters And Swordtails. Floaters kinda would be blimps. They would be organisms flying in the perfect temperature zone and flying with the baloons on their back. However, a sword tail would come. Using its super wings, it can fly lightning fast. Its sharp beak lets it tear right through the floater for food.\n\nOn EUropa:\nOn jupiturs smallest of the Gallelaio moons, there is a greater chance of having life than mars. The reason: Ice flows cover the surface. The ice flow tend to crack, bu recover. The process is also found on earth, and is now beleived that liquid water lies under the flow.\n\nThe appearance of life:\nSkating on the ice on Europa, An unnamed organism skates around, using its green body to undergo photosynthesis to produce food. Because It needs no air and makes food like plants, they need no mouths.\n\nVenus (What most planets moons probibly look like):\nOn a hot planet like venus, you need to survive insane temperatures. Eating rocks would also be good, for the fact that its mostly the only thing on the planet. Oh, and leave out the need for water. They cant get any there. \n\nThe appearence: \nStanding on the scraps of a russian probe, an oucher-poucher stands on 1 foot to avoid the insane heat, eating the scraps of the ship. The oucher pouncher needs no water, so it doesnt need hydration. Its body is also meant to withstand any type of pressure, for 90x earths pressure would surely crush it normally. \n\nPluto:\nPluto is made up of all types of ice. water, dry, though mainly methane. So drinking, again, is out of the picture. They might beable you suck moisture though. The sun is to far away for solar energy, so you can slash out all photosynthesis.\nThe appearence:\nPlutonian zittsles are almost small ice chunks with legs. They are able to last in temperatures in the climates back in the far end of the solar system. In the morning, they do whatever they can to stay cold, for they feel that -234C is almost the exact same as 103F for us. At night, they really get going. They send waves to eachother to communicate while the atmosphere is still up. When they really are energetic, they can spring in the air up to 30 feet. They use tiny mouths under them to suck moisture from the ice. They think that pluto is the only place for life; Everywhere else is to hot. \n\nTitan:\nTitan is the only moon that we know of that can support life. Its atmosphere is composed of mainly nitrogen, similar to ours. So it does have a green house effect. The ground is covered with ice, so they have to eat that for water. Also, they would need to keep warm, since although its not extremem temperatures, its really cold.\n\nThe appearence:\nBear-like Stovebellies are creatures living on titan. To keep warm, they have several features. They have a huge HUGE fur coat. The eat ice for moisture and to cool the ground the stand on. They also have a unique adaptaion to beath fire and fart out heat to go soaring. Salafishes, amphibious organisms, share a mutalion relation ship with stovebellies. They clear out ice blocks and act almost as dentistds for st

I think so.  Given the probable number of other planets (nearly infinite), it defies logic to think that Earth is the *only* place in the universe that life developed.\n\nI have not had any contact with extraterrestrials myself, however, so I am not speaking from personal experience.\n\nEdit 3/16\nAfter posting my answer, I watched a show on the History Channel about Meteors.  One of the things the show presented was a meteorite that is believed to have come from Mars and *may* have signs of fossils embedded in the rock, fossils of living organisms -- bacteria.  The meteor is called ALH 84001.  Here is a website about it:\n\nhttp://www.lpi.usra.edu/lpi/meteorites/life.html

I do ... I say "of course there is other life" ... I think that we would be huge ego maniacs to think that we are the ONLY life form in the entire universe!!

There could possibly be. Isn't it a little ridiculous to think that in all the galaxies that we are the only humanoid lifeforms? whether or not you believe in God!

So far, we can only detect fairly large planets around nearby stars in our own galaxy.  However, the number of planets we are discovering shows us that planets are very common.  There is no reason to think that other galaxies would be any different.\n\nWe don't have sensitive enough tools yet to detect Earth-like planets, but they probably exist. We don't yet know how common life, intelligent or otherwise, is in the universe, but considering how many galaxies there are and how many stars in each one, it seems as though there should be other intelligent beings out there somewhere.

No, there is almost certainly life within the Universe besides Earth, and there is certainly life within the Milky way besides earth.

There may be another universe we dont know, there may be species of different cell structure, we cannot say we are the greater body of another universe, there may be another species with much more advance technology, so everything is ????????????.
312883
Yes.\n\nThere is so much of this universe that we do not know.
1041987
Yes!  I think it could most definitely happen to us.  One would have to be very naive and simple-minded to think it could not happen.  Many people don't let current FACTS actually sink into their brain.  There are so many conditions on other planets that are habitable for small organisms.  Certain bacteria(extremophiles) thrive on extreme living conditions.  That is how life started on our planet, and if nothing else there are definitely other forms of life elsewhere.  But still, someone would have to be so self involved to think that there couldn't possibly be a other life form of superior intelligence.

Is there such a thing as close by planets?\nWith all that we see in the night sky, not just stars but galaxies as well, what are the chances that we are alone in the universe?\nThere has to be intelligent life out there. We are all just too far from reach of each other. And most likely, other intelligence would be like us and send probes. Living beings could not survive the long travel, space probes could.

All sorts, it is almost invetable that the universe MUST be teeming with life.\nBillions of planets, millions with life.  Possibly billions with life

I doubt that Earth is the only planet in the whole Universe that can sustain life.  There will probably be some other planets out there somewhere with some sort of life on it.  Whether it's intelligent life or not is another question!\n\nThere may very well have been life on Mars, or on other planets in our solar system at one point,  but we have yet to find it, or any evidence.
88197
yes, I totally beleive that there is life on another planet somewhere? If I didn't beleive that would that be a little egocentric of me (this world)
666417
Probably not.  That doesn't mean that we are the only life forms in the universe.  It only means that the probability that these life forms advanced to intelligent life, and have developed the technology to visit us is pretty slim.  Life on earth as we know it could be destroyed by a single meteor.

I don't think that fact means that it is obvious that there is other life in our universe, let alone intelligent life.  (BTW, I think you meant to say solar system instead of galaxy.  A galaxy is made up of many solar systems. )  I'd like to hope that with so many large galaxies out there that there is the possibility of one having a solar system that is capable of creating life.

Sure why not.\n\nJust look up in the night sky. There are so many starts we can see, and untold planets we can't. This is just one galaxy. There are so many more out there in the univers. It is really silly to think that with all those planets, ours is the only one that has life.\nOur planet is still a young one. I'm sure there are life forms on other planets that have technology we can't begin to comprehend

Well, if there are billions of stars in an average galaxies, and there are countless galaxies in the universe, even if there is an odd of 1 to trillion, then the probability of having life forms in other galaxy systems appears to be good. \nHowever, life-forms as we know on earth may not be duplicated elsewhere.  Ours is carbon-based.  It is not improbable for other forms of life to exist.  \nBecause of limitations to speed of light, and hence to travelling speed, we, earthlings, may never be able to encounter alien life, as some galaxies are hundreds of millions of lightyears (a lightyear is the distance travel by light in 1 year) away, that is it takes light hundreds of millions years to reach us from that distant galaxy.\nSo even if the intelligent life-form on the outskirts of our known universe were to evolved a million years before us, and if such intelligent life-forms were to be able to travel at the speed of light, they cannot reach us in another hundreds of million years.\nBy then, our enlarged sun would have scorched our earth into an uninhabitable region, meaning all lives on earth would be wiped out.
