Yes, and we are already here, to observe. Over the centuries, your planet was a curious place to visit once or twice and was not considered very interesting . Sure, your wars showed us how undeveloped you are as a species and your infantile,(in cosmic terms) dependence on god concepts does not bode well for you. We are now showing an interest in you because it is not often that we get to observe a species commit suicide. You are so close to maturing as a sentient species and it will be a shame to see you kill yourselves. There are just not enough of you becoming rational enough to force the issue. You let the least among you determine your fate, so be it.

It's been estimated by astronomers that the probability of life similar to ours evolving on a planet orbiting any given star is approximately 1 in a million chance. Being that our own galaxy contains upwards of 200 billion stars, then there should be about 200,000 stars in our galaxy with intelligent life on them.
Now, there is no reason to assume that the other stars would have intelligent life orbiting them right now. Our sun is about 5 billion years old, with the universe being 13.7 billion years old, meaning that most of these planets with intelligent life would develop it either before or after ours. We have been on earth for just a blink of an eye in astromical time, and will probably be gone in another blink, so the chance of any two intelligent life forms occupying the same galaxy at the same time is extremely small, especially since every intelligent species will eventually discover Element 92, Uranium.

No-one knows of course, but consider the following:
- life thrives in even the most inhospitable places on earth
- current abiogenesis work suggests the stuff of life is prolific
- life started on earth almost immediately (in geologic times) after it congealed
Based on these, it seems that self replicating molecules might not only not be improbable, but are perhaps highly probable when the following conditions intersect:
- a source of energy (sun, volcanic activity, other?)
- water
- hydrocarbons
There is some speculation that life as we know it basically evolved from clay that has somewhat of a self catalyst property. That isn't to say this is the only way life could evolve, but it might suggest that clay is perhaps another necessary ingredient.

Given the vastness of the universe, I would find it hard to believe that there is NO other life form in the entire universe. But I believe the conditions necessary for advanced life forms to evolve are rare. Thus, most of the "life forms" we would find on distant planets is probably quite small--bacterium and molecular sized stuff. Just my opinion.

If you consider every single planet in every single solar system in every single galaxy in the whole universe, my guess is yes. There is simply far too many planets out there that the probability that in all of them life would never happen by accident is virtually nil.

May be not in our solar system, but think on how many solar systems exist in the universe and the probabilities that life exists only in our planet.

As the chance that ANY life would happen by accident is "virtually" nil (i.e. smaller than the chances you'd guess what elementary particle I randomly picked from some point in the universe), I would say: probably not; the probabilities say not even life here formed by accident.

probably. there are so many galxies/planets out there so there's bound to be something out there. The only thing is that we haven't discoverd it yet...or have we?

/you can say no & you can say yes/my information says Earth is the one that there is lif on it until now but we don't know is there life or not but there is water on Mars in 2015 areal man will go to Mars to know is there life or not in the other planets no body knows is there life or not please thanks for your question and goodluck in space.

I think so. It's like you'll never know whether there are other universe outside our universe.
