basically probability of planet with evolved life

No, there is almost certainly life within the Universe besides Earth, and there is certainly life within the Milky way besides earth.

Answers:
No
and
No
Probability: Good
Reason: 100 Billion Stars in the Milky
Way Galaxy. Each star may have from 0 to 10 planets.
Of 1000 Billion Planets at least 1000 should have conditions
similar to those on Earth. Of those 1000 at least 100 should be
in the various stages of life formation. Is one in the present stage of human intelligence development right now? Who knows. The information will be hundreds of years old by the time it reaches us. Light from some stars seen in the sky this evening is reaching us after traveling through space for several thousands of years. So "Time" and "Relative Distance" are almost as important as picking the right Star and its planet.
Beyond the Milky Way Galaxy are 100 - 200 Billion more Galaxies
with about 100 billion Stars in each of them. So the probability
factor is quite large. Detection of those Stars and Planets is,
however, very difficult because of their being hidden behind our Stars. What ever you thought of as being vast, forget that, this is something really huge, mind bending in fact.

It is doubtful that it is unique. The odds are pretty good that there are some earthlike planets in orbit around some of the stars out there.
The sheer mathematics make the odds really pretty good. But the problem is how do we reach them?
You can bet they are working on it, but even as our technology improves all the time, they aren't anywhere near a solution to get out there.
The odds are pretty good too that life as we know it might exist in an entirely different form than humanoid.
We are still primitively attempting to get off earth with brute force and there has to be a more efficient way. Anti-gravity perhaps?
Who knows. We will have to wait for that too.
Relative to the kind of technology needed to travel the stars, we are using sticks and stones right now.

probability of planet with evolved life, then no. the universe is a BIG place......and i mean a BIG place. we can't comprehend the pure NUMBER of planets in our universe. i think there most definitely is life..... somewhere. probably A LOT of planets with single celled life. however, if any intelligent life evolved that could actually build technology (like us), i think that would be a lot more rare. but still, i'd say earth is not unique even in that respect..... it seems to me that a whole universe for just one species on one planet around one star in one galaxy.....would be an awful waste of space...and a great tragedy.

Given the numbers, its pretty insane to assume that we are the only planet in the universe with life. Now the chances of us discovering highly intelligent life on another planet, are probably pretty slim. For all we know, the first planet we find with life might be in the beginning stages of planetary evolution and may inhabit nother but large primordial beasts like dinosaurs. From a scientific standpoint, the discovery of life on another planet like this would be fascinating. But we might actually need to establish a galaxic civilization if we are ever going to find life on another planet. And this could take a million years. We have plenty of time provided that we dont blow ourselves up, or get destroyed by an asteroid. We have billions of years before the sun dims out.

The conditions for the existance of a planet similar to the earth elsewhere in the universe are not affected by the dicoveries of exoplanet. Right now, our best methods can only detect very large planets in close orbit to their star, and relatively close to our own solar system, surely this is a vanishingly small sample of everything there is out there. The only thing we can say at this time, is that earth is unique TO US; but there may be countless planets just like it, we just do not know how to estimate their number yet.

no.....to tell you the truth, i agree with everyone else. its true that our planet is the only planet that is known to hold intelligent lifeforms but that doesn't close out the fact that there may be other planets that can hold lifeforms that are way past our imaginations. its not that our planet is not unique at all. It's pretty special but only in certain areas and fields. we haven't even seen the whole universe. we don't even know if there is an end to this universe. sure, for right now you can say we are the most intelligent lifeforms, but i don't think we can think that for too long, cause i really believe that there are other lifeforms out there just maybe waiting to be discovered.

In the universe, no. In the milky way, probably not. That's why I think we need an aggressive exploration of Europa, Mars and possibly some other bodies in the solar system to determine current or past life off earth.

Earth is unique to the Galaxy because it contains Water and the Ideal Atmospheric pressure and temparature for nourishing life

Within our galaxy i guess it should be only earth that has non-microscopic organisms.....but as for the universe there are chances that pppl like us exist...atleast somthing like us......anyway that is going to take a long time to find out
