Is there life in an other planet?

Yes, there has to be.  The universe is immense with many galaxies, and many suns.  There must be a lot of similar planets out there somewhere, why should there be only Earth with life?  We might never meet any extraterrestrials, probably aren't supposed to, which could explain the vast distances.  Some other beings exist now, or were extinct eons ago, or are yet to be.  I think they are a lot like us, not made of electricity or silicon, or in only two dimensions like some sci fi.

life exists on other planets.  it may be something like bacteria, or something large and intelligent.  life was created by chance though, and Earth had 6 mass extinctions where each had the potential to stop life in its tracks.  ironcaly, the extinctions caused evolution to speed up, but thats getting off the subject.  if life is on other planets, which i amm sure of, they will be like nothing any human can think of.  look at earth and how only a continent away can cause large differences in animals.  the planet will provide different challenges for life and evolution to overcome, the life might not even have DNA and RNA, they may have a completely different nucleic acid/genetic material.  its unlikely we will ever find them within the next century, though.  we simply wont have the space travel capabilities.  in time, though, i am positive that we will stumble across life, may be just odd bacteria or could be something like the aliens from ALIEN or the Covenant from Halo games.  we just dont know.  lizard-men?  highly unlikely.

If you are referring to other planets that are habitable, I believe that mathematically there has to be intelligent life in other parts of the universe. Here is why.\n\n1. The Hubble Telescope estimates that there are 125 billion galaxies.\n2. Each galaxy has roughly 100 billon stars.\n3. If even 1% of those have planets and only 1% of those are habitable and only 1% of those have life, the odds are high.\n\nThe odds are extremely favorable for there to be extraterrestrial life. \n\nOne can use Drake's equation to calculate the chance of life in our galaxy. Multiply that result times the number of galaxies. See the second link below.\n\nA totally different question would be whether or not we would actually interact with extraterrestrials...\n\nI will leave that one to another Y! Answers Question

Yes, we will discover other planets that also sustain life, and we will do so within our lifetime.  I do not mean that we will physically go to these planets but we will discover this by placing much more powerful telescopes in orbit around Earth.  There is a definite signature that we will be looking for and that will be the presence of Oxygen in another planet's atmosphere.  If a planet does not have any oxygen in its atmosphere then it would not be able to support life.  There was a time billions of years ago on Earth when there was no oxygen in the atmosphere and at that time there was no life on Earth.  We may not discover other intelligent life on other planet's during our lifetime but i am sure that we will discover other planets that are supporting at least plant life if not primordial single cell life as well.

Exactly... nobody knows if theres life on other planets and its actually quite ignorant for people to believe that we are so superior that we are the only life on the universe.\n\nLife requires certain things to occur in order if its going to happen.  I can go on about this for hours... first things first... life in its simpliest for are anything that are self replicating.  It requires a perfect solvent for biological reactions.  Water is great since the properties of water surpass all others.  this is why you here NASA is trying to search for traces of water on mars... because with water and the right conditions, anything could happen.\n\nCurrently, theres only a limited number of known planets besides the ones in our solar system...  other planets outside our solar systems are hard to detect since they do not emit light of any source so they can no be seen.  The other planets are discovered by the wobble effects of the stars (look it up).  We do not know how many planets per star nor the types of planets they are (more than likely with this method, they have to be very massive like jupiter).

there hasn't been any found yet.... but... the possibility of life on other planets is very  high....  :)

There are many planets discovered (through pictures of many forms). There haven't been any planets discovered with life on them, but there have been many planets discovered.

There is alien  life. Perhaps not in our solar system but definately out there.\nNow this life could be simple microbes or anything like that.\nIntelligent life may be out there too, it all depends on how things developed after the big bang. There   MUST Be intelligent life out there.. There's none here!!!

No. Icy moons in the outer solar system may very well be teeming with life. Beyond our system there is definitely other intelligent life. \n\nHopefully a lot more intelligent.\n\nBeam me up, Scotty.

It is more likely than not that there are many planets in the universe with life and many of those may have "intelligent" life.\n\nWe have just only obtained the ability to detect planets in other solar systems and we can only detect very large ones. We do not have the ability to detect Earth like planets.\n\nWithin our own solar system, we have yet to find undisputable evidence of life on any of the planets we have activley searched for it. Many scientists are optimistic about finding microbial life forms within our solar system though. There are still pleanty of places on Mars, for example, that we simply haven't looked, and there are many moons in our solar system with the potential for supporting microbial, and even more complex life forms. Jupiter's moon Europa is a good candidate because it is covered by a sheet of ice and thought to have liquid water oceans underneath. Due to Jupiter's gravity constantly tugging on the planet, it is likely geologically active and thermal vents may exist in it's under ice oceans. Here on Earth, underwater thermal vents are teeming with life, even though no sun light reaches them.

People have always wondered\nwhether or not life exists \nelsewhere in our solar system. \nSomewhere besides the Earth. \nWe humans have never accepted the idea that it is only on the Earth that life has occurred. From earliest times when we peopled the heavens with gods, goddesses and supernatural beings, through our space exploration activities of the 20th Century, we are driven to decide the question:\nIs there Life on Other Planets?\nThe question of UFO's and intelligent life on other planets has become very popular. Many fashionable scientists speculate about the possibilities, insisting that we cannot be alone in the universe. Alien life is the subject of hit television shows and movies, and is also a common belief of many New Age religions. Many people have asked what the Bible has to say about this subject.

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?

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..

"Are there any other life forms on other planets?"\nProbably, we just have to find them (or they have to find us).\n\n"Is it possible that when we expire we will be born on a other planet?"\nThat is a theology question, not a science one.

With the nearly infinite number of stars out there, it is reasonable to expect that life has developed on another planet. However, we won't know for sure until we actually encounter that lifeform, and that may be a long way off.

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

I don't know about the other 8 planets of our system because no life has been found yet but there are other galaxies and it seems arrogant to believe we are the only ones made with so many possible environments for others.
