Yes. The number of stars and potential solar systems is so large it defies comprehension.
The probability a human could reach such a planet, even if it were identified, is zero. It would take MANY lifetimes to get there.

To make the universe somewhat comprehensible, there's more stars or suns (whatever you want to call it) than there are grains of sand in EVERY beach in the world.
To imagine this planet is the only one in the universe that can accomodate life, you've got to be crazy. If there's that many suns in the universe imagine if they on average had 2-3 planets per solar system. That'd be 2-3 times all of the grains of sand on Earth.
These planets that could accomodate life would take hundred IF NOT millions of light years to get to. According to the special theory of relativity (http://en.wikipedia.org/wiki/Faster-than-light) you cannot go faster than the speed of light which has also been agreed upon with the physics community.
What is possible though, is a wormhole (http://en.wikipedia.org/wiki/Wormhole) in which you can travel to another side of the universe in a shorter period of time.
The idea of matter cannot be created nor destroyed EXCEPT during nuclear explosions brings us to black holes. If even light cannot escape a black hole, where does all this matter go to?
Just some food for thought.

its so possible that i am 100% sure there is, i said i am, not everyone. there is over 150 billion galaxies each with over a billion stars, but ill say a billion just for the sake of easy math.
so thats 150 quintillion stars, im sure each have atleast some planets even if we cant see them. the chance that we are the only life is so very small. the universe is massive, massive beyond human comprehension.
weve already found planets that most likely have water on them, the nearest earth like planet is 20 lightyears away, which is actually a very short distance in terms of the universe.
so there is definately life somewhere else out there, dont let anyone tell you different. there isnt, however, aliens here on earth. thats just idiotic.

The answer is NO. There is no other planet that we can live on. There might be some planets that we could live on if we knew about them and had a way to get from here to there. We can be quite sure that there are no such planets nearby - say within 100 light years. It is an interesting amusement to think about other planets with civilizations, but humans will never have contact with such civilizations and humans will never travel even as far as the nearest star, 3.5 light years away.

Based on the rate of discovery of other solid planets nearby (within ~100 LY) ... for the whole universe, yes there is most likely another earth-like planet. Even in our own galaxy there is probably another earth-like planet.

Not to live and breath and move about unrestricted as we do on earth. If you want to live underground or in a space enclosed area or go about in a space suit all your life, then maybe you can find someplace but it would have to at least have the ability for it to have some sunlight for warming the planet or a way to make energy to use for keeping warm / cool whichever was needed. Most of the planets out there do not have that ability or any ability to maintain life as we need it on earth.

Yes of course. When life on this planet ends, Humans will find a way (Evolution) to survive, and regardless of your beliefs, things do change (adapt) to new surrondings. So, I think someday yes, man will exist on another planet other than Earth.

yes their are millions of galaxys and their might be a planet just like earth i think this is way UFO and aliens came from but their spacecraft can travel at speed of light as seen on TV.

In our solar system the answer is no, however in our Galaxy there maybe one or two others out there. In the entire universe their maybe millions perhaps billions.

Universe, that's possible. Within our solar system, that's not probable.
