Earth is the only planet having life in it.but,it was discovered that mars also has vapour,where it is possible for us to live.Do u think we will have two planets consisting life in future?

There is no evidence to prove that there is NO life elsewhere in the universe actually - I took an astronomy class and there is a lot of debate about it ~ there could be life elsewhere..

Mars does have an atmosphere but not enough, and not in the right proportions for us to be living there without controled environments. There has been some debate over whether or not terraforming would be possible and effective--this would give us a thicker atmosphere more like ours in theory and, depending on how it is done, get life to start to develop.
We will probably "colonize" Mars in the future. In our lifetime there might be a station there, and in future generations there could be families living there. Really changing the planet (through terraforming) so that we can live there similarly to how we live here will probably not happen for a long time if it ever does happen - the science is still a little shakey and there are tons of ethical and even spiritual issues involved in it.

Mars does have an atmosphere, but is is very thin and has no oxygen. Photos from the Mariner mission satellites orbiting Mars showed cirrus clouds. But the resemblance to Earth stops there.
Mars' atmosphere has no protection from solar radiation like Earth does. Which means the sun would kill you if you tried to live on Mars, even though the temperatures are sub-zero. On Mars' equator, in the summer, it can get up to a toasty 60 degrees, but then the night temperature drops to minus 100.
Mars is uninhabitable. We would have to look elsewhere in the galaxy for a habitable planet. I have no doubt we will discover habitable planets with the new line of future orbital telescopes. Getting there is another matter. The nearest habitable planets are probably at least 100 light years away. That means if you travel at a good fraction of the speed of light for 150 years, you'd get there.
I think if we were to actually build a starship like that, it would have to be more of a Noah's Ark.
Of course, if the planet is already inhabited, we would be the aliens from outer space.

well before i answer the question, just read the following.
In 1998 NASA landed a space ship on mars. It scooped up some sand and brought it back for research. It was found that the sand contained a bacteria.
Now if you would remember, even on earth it is believed by Lamark's theory that all organisms come from one species which slowly evolved. Maybe that was the beginning similar to what happened millions years ago on earth. Mars has vapour but it doesnt have it in liquid form. Neither does it have a atmosphere. It doesnt save it from the ultraviolet rays. But the bacteria thing claims that mars is changing. Its temperature is similar to the earth. So the rest is up to you. I didnt basically answer your question cause the answer lies in the question itself. The answer cant be gotten unless the question is rotten. Some years from now it will be rotten. Either the question, or its idea

They have found signs of bacteria existing on Mars, but they're not absolutly sure. There's really no proof that any planet in our solar system consists of life.. yet. Possibly, in another solar system there may just be another planet that does have life on it. But until we get the proper technology to explore that far into space, we may not know for a while. But yes, I believe it is possible that there is at least one planet somewhere that does consist of life. The thing is, the planet must be in the most perfect conditions for life, it would be hard for a planet to be much like ours.

NASA uses sterilization procedures to hopefully kill off Earth bacteria in the hopes of not "polluting" the experiment. There are many set backs for higher based life forms, but the 'Red Planet' would be a welcoming home to many different types of Earth bacteria. One day I suspect that our sterilizations will fail and something will begin multipling on Mars at the very least. Whether or not it eventually gets teraformed into something habitable by Man is the provence of grand dreamers and sci-fi writers in our lifetimes.

till now no certain assurance has been given that life is possible on mars so thinking of that which has still not been confirmed is not a matter to debate and think but yes if confirmed that life is possible on mars we will be having 2 planets to live but it wouldn't be easy to start a new life in a new planet .........its very difficult job to do but to fight with the problems and reach to success is the motive of each and everyone and NASA and other space organizations for past many years are doing this only....

Planets are evolving .Change is the unavoidable and essesential character of nature.but it will tqke its own tie . We might not e there there to witness such changes .Even the solar system is sure to meet its doom in a white dwarf or a blackhole and there will be none to record the event or remember the event as all lives in all planets even if there is any without our knowledge , in the solar system will vanish into the black hole or white dwarf and undergo a nuclear reaction for thousands of eons before it bursts into a new solar system and gies rise to new lives from the stage of a signle cellular organism repeating the story of the existing universe as pronounced by Lord krishna in Bhagavad-Gita and as predicted by the cosmologists and .scientists of the 20Th century.They cycle of creation , sustenance , annihilation and re-creation is nature's sacred duty and there is no stoping of it .Thre will be no planet at all in the solar system when the sun exhausts it's fuel .There is no questioin of a second planet com ming into existence in the present solar system.

The thing is that it would be such a waste of space if we were all alone. Mars has "evidence" of water, and frozen CO2/water on the poles. There is a chance a place with water has life on it, but the truth is we don't really know yet.
We might send people to Mars for long periods of time one day. But more recently, it'll only be for research and exploration. I doubt (but I hope I am wrong) that WE will see "regular" people go there in our lifetime.

well, in the future, i would think so, but for now, i don't think so. mainly because the other planets really don't consist of life.. another thing, it is proven that there's no oxygen in other planets, instead, there's nitrogen, lots of nitrogen w/c would grave us to death.. there are proofs that there's no life on other planets----no people, animals, plants nor aliens discovered to be living in and among these planets, so logically, no life out there, just a bunch of nitrogen, dirty dusts and rocks circulating the whole planet.. oh another thing, they have no atmospheres w/c would protect their insides from harms such as asteroids, filthy air, etc...

As long as our technology can support the needs of life to Mars in the future. As others say, The universe is so big that it is possible for life to exist anywhere. Maybe they are in the stage of Devonian-like or Jurrasic-like era right now, we do not know! But I know, the dimension of time will only tell us what would happen so...
