Look... understand this logic..
The probability of getting an earth like planet is very less...
But universe is too large ...it nullifies that improbability...
Other things..
our one is hydrocarbon--oxygen formof life...
there can be some other forms too...
like nitrogen-c-14 type of life which can use cosmic rays as its food and enrgy source (that is hydrocarbons in our case)

that depends on what you mean by life. If you mean complex life like humans then the odds are slim but there are MANY galaxies in our universe so it is probably safe to say that at least one of those galaxies has at least one world where there are complex life forms.
But if you mean life including microscopic organisms than the answer would be a lot higher. We know there was life on Mars. And according to a recent report from NASA there may still be life on Mars.(see sources) We also know that microscopic organisms have been found to survive in all kinds of harsh environments. So I believe it's safe to say that life IS possible on interstellar/intergalactic planets.

A planet would have to be in proximity to a source of energy,likely a star.
In interstellar or intergalactic space you may be correct in saying it is not possible.
I would prefer "not probable"

Your question could be better rephrased as "life is not possible in exoplanets (planets not of our solar system)? True or False?"
We thought that Mars was too cold and dry to house water but now the evidence is proving that liquid water is still present. And where water exists, some life forms may exist.
There are billions of stars and many planets have been discovered. While most of them are too big (that is how they have been discovered from earth) and too close to their suns, there could be some planets at the optimal distance to support life.
So, it is better not to assert that life is not possible out there.
Good luck.

No, we don't know enough about the billions of stars in our own galaxy, much less the stars in the billions of other galaxies, to say that life is not possible on another planet.
With all those billions of billions of stars out there, why couldn't one of them have a planet orbiting it that can sustain life?

No, it is not correct to say that. Maybe yes on the interstellar part, but not the intergalactic part.
There is no proof that it is true - so you can not assert it.
