No because no planet has exactly the same living conditions which ours provide. And we know thtat any slight change in the composition of gases or the distance of the sun in relation to the earth can have a darmatic impact if not fatal one on our lives

it would depend on a number of variables, the mass of the planet the distance from nearest star chemical composition etc. the most crutial factors for fininding life on a planet for sustaining life a) the type of star, followed closely by the distance it is orbiting from the planet. if the star was a typical star like that of the sun, i think its a G type star, and nothing to hot or exotic then the crutial factor becomes the habitale zone, distance planet is from star. If the star is hot then the proportion of radiation that would be damaging to life that we know would be much higher than that we recieve from the sun. there would be x rays uv rays etc these can also come from other stars in the region if it was an active star forming region. If the star is okay then finding a planet in the habitable region where liquid water can exsist is important. If the planet was massive then the gravity could stop us from living there by crushing us. the chemical compostion of the planet would be important since it would have to contain large abundances of O, C, and all the other elements esential for life.
|I have read somewhere that mars would be habitable within a hundred years if we started a greenhouse effect to haet it.

If the atmosphere of such a planet could support us, and the gravitational pull of the planet was not too weak or too strong for us to handle theoretically we could live on other planets. As of current our knowledge of the universe in which we live is extremely limited, and we do not have any data or confirmation of a planet within range of Earth that can support human life for extended periods of time... Though I am certain that there are planets like that out there, we have yet to locate them and confirm their existence.

With the size of the universe, I'd say definitely - however, we will never be able to reach them unless some miracle breakthrough in space travels occurs, due to the huge distances and time involved - but it is very likely that with the trillions of planets out there that there is one with conditions like earth, though I'm not sure whether life would have evolved on it or not...

I think so, we just haven't found it yet. No planet that's close is inhabitable. But, look at the sky at night. Look at all those stars. Think about how many planets there are surrounding all those stars. Surely one of them is similar to Earth.
Just so you know, I also believe that this planet (the one we've not found that's similar to Earth) is inhabited already.

Hope not because one day are home is going to have to out there with the stars.
