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!)

∙ 11y agoSorry 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.

∙ 13y agoWe 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.

∙ 11y agoYes, 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.

∙ 9y agoIn 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.
Wiki User
∙ 12y agoAbsolutely, at least in bacterial form.

If we discovered water on another planet, it means that humans may be able to inhabit that planet. It would be a big break through for scientists. Another answer may be that other organisms or bacteria may be able to live on that planet, meaning there could be life on another planet but Earth.
Possibly Mars. But so far there isn't any life on it.
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
No-one knows for certain
is there life on the new planet is there life on the new planet
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.
No. There could possibly be undiscovered life, but no humans.
Possibly, but the new planet will not have any life forms. (Most likely.)
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.
Life on Another Planet was created in 1983.
Nobody actually knows, but their is a theory that life came to this planet on the astroids that formed this this world, which could have grown on the meteors or came from another planet.

The ISBN of Life on Another Planet is 0-87816-014-0.
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.
Yes! Life could be found on planet earth!
