out of all of the planets out there.are we the only ones living in this universe?

Answer 1

We don't know. We have plans to explore as far out as we can, but until we find other life or search every corner of the universe, we just don't know.

Answer 2

We are the only planet that has 'life' on it, to the 'best' of our current knowledge. That doesn't mean that we are the only beings 'living' in this universe. Look around you at all of the 'other living things' around you. If our world is 'so full' we STILL don't know of every different 'type' of thing living, HOW could 'the whole universe' NOT have different 'life forms' and different intelligences?
I'm a Catholic, and I believe that God 'created our whole universe' ... and for some reason he put us 'humans' on THIS PLANET and gave us what we needed to 'rise to the top' of the evolutionary ladder ... but that does NOT mean that he didn't do that on many other planets ... it only means that 'we are not ready yet' to 'meet' the other beings ... and we may not be until we are 'dead' and in Heaven ... because then we won't be 'human' any more, but 'heavenly beings' who can communicate without 'words' ... and THAT will be when we know 'the rest of the story' ... at least as far at 'the people alive on Earth now' are concerned.

Answer 3

In 1961 Fran Drake created the "Drake Equation" which makes estimates of how much intelligent life is out there. Go to http://www.activemind.com/Mysterious/Topics/SETI/drake_equation.html to have some fun with it. You input what you feel are reasonabe numbers and percentages for planets that form and could sustain life and the Java program calculates the Drake Eq for you. Note, even though there are "billions and billions and billions" of planets out there, as Carl Sagan would say, I you give the Drake Eq extremely low probabilities for creating life then we are it...at least in the here and now. The Drake Equation also requires an estimate on how long intelligent civilizations live. The math is fun, and you can learn some things by studying the result, but there are way to many over-simplifications to ultimately trust the results. It may be good to give you intuition about this problem though...

Answer 4

No....according to the hetetroph hypothesis (the most accepted version of the Earth sequences) life is really easy to make over such a great time and millions of planets out there the same thing can happen on a different planet.And that's just life as WE know it. There could be different species that live entirely different, more efficient, and don't need oxygen as we do.

Answer 5

As far as it has been observed by our top Scientists in the Universe ,we are the only Animal life out of all the observed Planets with the Earth sticking out like a sore thumb.

Answer 6

With apology to Bill Clinton, it depends on what you mean by "living". We ARE the only ones living at our level of technical expertise that we know. We are becoming more convinced that live at the unicell level MAY exist on Mars, one of Jupiter's Moon or Titan. As for other life at other levels of complexity, there should be enough sites that some type of life would exist somewhere. But that seems as far as it goes at the level of scientific certainty or speculation.

Answer 7

Possibly. In a book entitled RARE EARTH the authors make the case that for life to evolve to our level, the odds are EXCEEDINGLY remote. They make the case that life itself probably isn't all that rare, its probably common, but it probably never gets much above the algae stage.
If you don't feel like reading the book, and it is very readable, go to wikipedia and type in "rare earth hypothesis" or just use this link:

http://en.wikipedia.org/wiki/Rare_Earth_hypothesis

It will tell you probably all you need to know about this important idea.

Answer 8

So far thats what it seems with the research we have, but I'm sure there is some place else out there with life. We haven't seen all the planets out there yet.

Answer 9

thats a big question and no one knows that answer for sure. but ill give you my answer.

there are over 150 billion galaxies, each with well over a billion stars but just for the purpose of easy math well say that its a billion per galaxy.

thats 150 quintillion stars. most with planets even if we havent been able to see them quite yet. thats 150,000,000,000,000,000,000 chances for life. well over that, actually its probably closer to a sextillion chances for life.

so the odds of us being the only life in the universe is 1/1, 000, 000, 000, 000, 000, 000, 000

Answer 10

considering the immensity of the universe, I suspect there's more life out there. But who knows? Some scientists doubt that there's any more life out there.
