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!)

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.
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.
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
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.
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.

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!
A 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
