  • That's really an impossible question to answer. It may, it may not. Maybe someday we will find out but it's just not knowable at this time.
  • It has been determined mathematically that it is more probable than not.
  • Of course. It's simply highly and extremely improbable that with the vastness of the universe we're the only life supporting planet.
  • How could there not be? I mean if our systems revolves around the sun which is really just a star then there has to be other systems surrounding other stars that we see in the sky, and out of all those places, there has to be other planets that are habitable. It would almost be ridiculous to deny it.
  • Yes, but it may not be life as we know it. +5
  • yes,there are so many planets one must hold life forms.+5
  • I respectfully disagree with all of you. Roughly using scientific estimates known today, 1 in every 1 billion (that's 1/1,000,000,000) planets in the universe has an Earth-like atmosphere. This number is used as an estimate and can not be verified however.What is the probability of life beginning on Earth by chance? If we estimate that there was a 1 in 10 billion chance (that's 1/10,000,000,000) that life would begin on Earth and then apply that statistic to the universe.In simple probability studies you simply multiply the two probabilities together to see what you get. In this case 1/1,000,000,000 x 1/10,000,000,000 =1/10,000,000,000,000,000,000. This is the probability (according to our hypothetical calculations) that life will exist somewhere else in the galaxy. That is the same as saying there is a .0000000000000000001% chance of life existing elsewhere in the galaxy. Secondly there is no proof of life existing anywhere with our telescopes, studies and space exploration programs.
  • You cal this a life?
  • Probably, but not necessarily AS WE KNOW IT.
  • It's a near certainty. It may even exist in our own solar system (beyond Earth). Mars, Europa, and Titan are all possible sites.
  • yes it has to
  • I'd be willing to go so far as to say DEFINITELY! ABSOLUTELY! Will we ever see it as a species? Hell no.
  • Yes, I really do. One day, they will come and visit the earth.
  • our galaxy... im not so sure. but in another galaxy i think no doubt. of course there is.
  • Do you believe in life after love?
  • Yes, I really am convinced there is. Here's a video to show what I could be typing, to save myself a ton of time. http://www.youtube.com/watch?v=mcBV-cXVWFw It's a video about the Hubble Deep Field
  • It's possible.
  • sure I do
  • Be it algae in a comet, Sagan's jellyfish in the gaseous layers of a gas giant or nanoscopic lifeforms on a particle of dust on a cold, dead planet. Extraterrestrial life probably does exists somewhere out there in the reaches of our galaxy. We'll probably only find it in our lifetimes if it's in our own solar system though. As for intelligent lifeforms. I doubt we'll ever get those famous radio signals from beyond the Kuiper Belt less it be from from early space probes like Pioneer and Voyager. Certain people seem to contradict themselves logicaly when speaking, saying how advanced civilizations (more so than us) will likely use radio. It's like asking a man from 1809 what people will use to submit answers and questions into an international forum of people in 2009. He'll likely suggest paper letters sent by sailing ship and caravan and not digital transmissions over wire then through lazers beamed to satellites and back down to be transmitted into wire and through radio and what-not depending on the network setup the individual recieving the transmission is using. And besides, space is a very noisy place. Radio waves would probably get distorted beyond recognition over long durations and who knows, we could be at this very moment being bombarded by alien music and late-night radio shows with guests calling in about how they abducted some poor human on a distant planet and unable to recieve them only to hear the static fuzz of background radiation. Also who's to say it was made by intelligent beings in the first place and not naturally formed by the processes of nature herself; such as that of the radio emminitions of Saturn's rings.
  • No humans created the concept of alien existence dor entertainment
  • Definitely, there has to be life elsewhere. +3
  • 100% ... we came from there ... we are there now ... a place which is infinite ... must have life somewhere. Peace
  • On a planet called "marclar" there is intelligent life. they are called "marclars" and they refer to every person, place, or thing as "marclar".
