There are approx 5x1022 stars in the Universe. (see a previous Wiki question)
Say only 1 in a million has a planetary system.
Say only 1 in a million of these has a planet capable of supporting life.
There are therefore approx 5x1022 / 1012 = 5x1010 'earth like' planets.
Suppose only 1 in a million of these actually evolved intelligent life.
There are at least 1010 / 106 = 10,000 intelligent races out there!!
At least one individual from one of these (apart from me) is probably sitting at their computer working out this very fact.
_______________________
As appealing as it is to imagine that there are thousands of earth-like planets, there is not yet any evidence that any exist outside of earth itself. The numbers are compelling, but they are not proof. Rather than getting caught up in the wildly exciting prospect of finding planets that harbor forms of life that we would recognize as such, it is more important right now for us to continue refining our abilities to accurately detect smaller and smaller planets that have even a chance of being earth-like.
The answer is unknown.
Scientists have been puzzling over that question for years and they still haven't found an answer.
Humans are only able to land on a few planets due to the time it takes to travel so cannot fully explore each planet.
ANOTHER ANSWER: By the way it would be very egotistical of us to think that we are the only life in the universe .... (that would be a lot of wasted space if we were!)

There is a possibility of life existing on other planets beyond Earth, but this has not been confirmed. Scientists are continually searching for signs of life in space through missions and observations of potentially habitable environments on planets and moons within our solar system and beyond. Further exploration and research are needed to determine if there is life elsewhere in the universe.
Sorry but the current research has not proved anything in that line. So that means we only know of life on planet Earth as for now.
But we have only begun to search, and several Jupiter-like planets have been discovered orbiting reasonably close suns. As our technology improves, we will be able to detect more planets, and we will be able to detect smaller planets. We don't yet know whether or not other planets harbor life as we know it, but there is nothing that rules it out.
There are many other planets in the universe but not to support life that we have discovered but in such a big universe there probably are many planets similar to ours and capable of supporting life. Whether or not we will ever be capable of discovering any of them is another matter.
We have not much of a chance, though a star nearby called Vega has a doughnut shaped cloud around it, and we're hoping that cloud becomes lumpy, and the lumps become clumps and the clumps become chunks and the chunks become rocks and that all ends up as planets. And if we find a planet with a similar distance from a star around the same heat as our sun, well, there's a 60% chance of finding life on that planet. so yeah Vega could have planets if that cloud becomes lumpy, and if Vega gets planets the formation of planets will take a few million years and then the sun will be dying, and not much chance of getting to that other planet with life (if there is any) in time to survive.
Yes, they have found a planet quite recently that has the same kind of climate as Earth and consequently scientists and astronomers think there is life on the planet.
Edit: I try to keep up-to-date on this question. I must say this answer is news to me. Are you sure? I heard that "Kepler" found a planet in the
"habitable zone", but that's not quite the same thing.
In view of the discovery of liquid water in several place in the solar system the existence of primitive forms of life is likely, but the chances of anything as complex as a bacterium are small.
Absolutely, at least in bacterial form.

Why would the discovery of liquid water on another planet be important?
The discovery of liquid water on another planet would be important as it is a key ingredient for life as we know it. It could indicate the potential for past or present microbial life, and could provide insights into the planet's habitability and potential for supporting life in the future. Studying liquid water on another planet could also advance our understanding of planetary formation and evolution.
What other planet besides earth can have life on it?
Mars is a planet that scientists believe could potentially support life, either currently or in the past. Jupiter's moon, Europa, and Saturn's moon, Enceladus, also have subsurface oceans with conditions that could be suitable for life.
Is there any other life in other planets?
earth is the only planet known to man which has life but there is a huge possibility of life or a different type of it existing on another planet.scientists are contantly working to find life on another planet
Is there another planet and if so is there life?
No-one knows for certain
Earth has abundant life dou you think that other planets or moons might support life If so which ones which characteristics of the planets or moons might be conducive to life?
It is my personal opinion that Earth cannot be the only planet that has abundant life. I believe that if life is going to be discovered on another planet that it will be the newest plant to be discovered, planet Kepler 186f.
What is the twin star theory?
The twin star theory is that there may be another star similar to the star we call "the sun" that could possibly make life on another planet possible.
Are there any humans living on Planet Saturn?
No. There could possibly be undiscovered life, but no humans.

When the sun explodes and everything is gone will another planet like earth form?
Possibly, but the new planet will not have any life forms. (Most likely.)
What planet in our solar system is most habitable?
Earth is the most habitable planet in the solar system, which is why there is so much life on it. As far as we know, no other planet has life on it. Mars could possibly support human life, with supports to help them.
When was Life on Another Planet created?
Life on Another Planet was created in 1983.

What is the ISBN of Life on Another Planet?
The ISBN of Life on Another Planet is 0-87816-014-0.
Is there another planet that's a replica to planet earth?
In a parallel universe, possibly. In ours no, at least unknown to us. It also depends on what you define as a replica, like land-life-and water, or literally a copy.
Can life be found on planet?
Yes! Life could be found on planet earth!
Could people put life on another planet?
Depends... if we manage to create the right technology to travel 20 light years to our nearest 'Goldilocks' planet, then yes its possible and i hope that does happen during our life time...living on another planet would be so awesome :D
What does extraterrestrial life mean?
A life on another planet
