Do you believe there's life on other planets?

The universe is incomprehensibly massive. There is no way that we are the only rock able to sustain life.

It’s certainly possible (and very likely) that there is life on other plants. Especially those that rely on symbiotic relationships with bacteria to get the nutrients essential to their survival. Or plants that are hosts to epiphytes such as is common in tropical climates.

I certainly believe there is the potential for life forms on other planets. As many heavenly bodies as there are in the universe, I think it might be pretty much mathematically impossible for there not to be life elsewhere. As far as intelligent life forms, that may or may not be stretching it a bit but who really knows for sure?

The chances of there being life on other planets in the universe are high. We’ll never know, of course, since it is unlikely that there will ever be ftl (faster than light) travel. I suppose there could be signals that indicate another civilization out there, but SETI (Search for ExtraTerrestrial Intelligence) has been searching for decades with no luck. Given the apparent likelihood that life is quite prevalent, this is fairly surprising.

One possibility is that the signs of civilization are just too faint to detect. Another is that life doesn’t exist out there; only here.

I don’t think belief has anything to do with it. Either there is evidence, or there isn’t. Right now, I’m agnostic on the question. I can see by your beliefs about the moon landing that evidence probably doesn’t mean as much to you as it does to me. So my answer won’t mean much to you.

I absolutely believe that there’s other life on other planets. I would find it highly improbable that our tiny speck of dust, orbiting a non-spectacular star, would be the only place in the vastness of the universe where life has developed. It’s truly amazing to sit and think about it, right?

As it stands now though,there is no evidence of life beyond Earth, but that doesn’t mean it’s not possible.

I think there IS life on other planets, HOWEVER, I don’t have a problem thinking WE may be the only ones.

Yes.

Yup. I think so given the massive size of space.

There probably is life on other planets but it probably isn’t recognizable to us. There has to be. The question is whether there is intelligent, interesting life on other planets.

There almost has to be within this seemingly infinite space we know very little about. My guess is that there are civilizations out there that are more advanced than us… We just haven’t met and possibly never will before earth’s life is over. I sure hope we find something in our lifetime, but humans have probably thought the same thing since we evolved.

EARTH is not the only planet with life ,its just we have not found THEM and THEY have not found US .
well joe public doesnt know that other life has not got intouch with EARTH.
as for the neil armstrong landing on the moon i do not think that happened if it did happen,the why has it taken so long for NASA to place someone else on the surface? and dont preach about it costs 20 million

Space is indeed large. Sheer probabilities would indicate that yes, humanity is not the only life in existence. The question though is whether this life is sentient or not, as well as when it existed (the past, the present, or the future), and how far along its evolutionary chain it is (imagine super smart aliens meeting up with Neanderthal instead of homosapiens).

The best chances for finding other sentient life are to get into space and start leaving signs. We may be the first ones in our age group to develop interplanetary travel, and thus we would be the “grey skinned creatures” to another civilization. Hopefully we would bring a message of peace and establish a mutual existence instead of jumping straight to war.

There has to be… I think Mrswho has it right.. the real question is whether there are actual civilizations out there to be discovered.

Then we can book space trips to visit strange new worlds for vacations.

I’m 100% sure there is life on other planets. Where “is” is a general term not bound by the temporal elements of its grammatical use. There probably “is” life on other planets even as we speak, but the distances are so enormous that it’s practically impossible to meet each other.

So, my guess is that, by the time we figure out a way to travel to those other planets (whose light started travelling to us centuries ago), there will be no life there to find. Assuming that such travel is even theoretically possible.

For me it’s like two ants sitting on a beach in a gutter in New York and wondering whether there are other ants in Australia. Assuming they do find a leaf to get on, the chances of it ever even reaching the ocean are almost zero. And even then, the ocean would be the Atlantic, and the currents would take them to Scotland instead.

And the real distances (and intellects) are by analogy far larger than the ones I described (think of an atom wondering whether there are other atoms like it on the moon).

It would be quite arrogant to think that in this vast wonderful universe we are the only ones.

I highly recommend the book Rare Earth http://www.amazon.com/Rare-Earth-Complex-Uncommon-Universe/dp/0387952896/ref=sr_1_1?ie=UTF8&s=books&qid=1236807451&sr=1-1 The author contends that life of the single cell variety should be relatively common, the chief impediment being water in liquid form, and could conceivably exist in our Solar System. He argues that more complex forms of life are highly unlikely. He does a good job of refuting the notion that Earth is an insignificant planet and points out some special characteristics of our planet that make it conducive to life.

I think there’s probably at least 2–3 places even within our solar system that have life (there’s a high possibility as we speak of life on Mars). But yes, intelligent life is unlikely. Then again, no matter how rare Earth is (and yes, it is), there are countless galaxies in the universe, with a practically infinite number of solar systems which makes another rare Earth more than just possible. The problem is that if it existed 8 billion years ago at a galaxy 3 million light years away, there’s not much point in hoping to meet little green men.

without a doubt.

the question is, Is there life on THIS planet?

As to, Do I believe there is life elsewhere: at present, no; but maybe later.

I can’t believe there is NOT life on other planets but thinking about the fact that the universe makes my head spin :D

That meant to say, thinking about the fact that the universe apparently never ends makes my head spin.

No. As much as Carl Sagan and the Drake Equation makes a form mathematical sense.
I believe the amount of complexity the universe has is needed just to enable/support life on this planet.

I am absolutely positive that there is other life out there in the universe somewhere.

@ChazMaz Really? Even with the the universe’s infinite size. What about the prospect of a multi-verse? (@Leanne1986, if that doesnt make your head spin.) Do you really think that with aaaalllllllll of that space there is not a single life form or piece of organic material.
