I could just be stupid and say yes there is life out there - me for one. However I think you mean life on other planets.
Get this figure in your head if you can. There are as many stars (suns) as there are grains of sand on every beach on earth. Scientists are discovering more and more planets in orbit around some of the nearest stars within the zone they feel compatible for conditions that would allow life to evolve.
When life evolved on earth it was a pretty nasty place with poisonous gases, extremes of temperature, lava erupting everywhere, earthquakes. You name it and it was happening. However, life evolved so the odds on life being out there is very strong but probably nothing like us.
As to intelligence, thats another matter. We have been on earth a relatively short time and could be killed off very easily so its possible that great civilisations have lived and died in the universe before we even got going. Its also possible they are too far away to be spotted via radio waves which is why there is now a search going on to spot laser light signals as it seems likely that advanced civilisations could send a message out in that way.
It could be that life exists but very few with the brains to ask the question "is anyone out there". It could be that they just haven't developed in the same way as us and will always be "primitive".
You may also ask the question "Is it safe to advertise that we are here?" Think about it - what did the so called civilised europeans do to the less developed parts of earth?
Live long and prosper inquisitive one. Keep asking the questions.

It's almost a statistical impossibility that we are alone, considering there are 300 billion stars in the milky way alone, and hundreds of billions of galaxies like ours.
Also, in just a few weeks observing a portion of the sky the size of a full moon we were able to find 16 extrasolar planets, and there are appx. 250 planets already identified outside of our solar system. There has to be life out there somewhere.

Why do I have to believe something? I have an open mind.
There have been hypothetical scenarios on both sides of the argument. One fellow worked it out to a chance of less than a thousandths of a percent that life could exist elsewhere and others have proposed millions of other "earths" harboring advanced civilizations. What do they have in common? They all have a book for sale. Why waste brain cells trying to know the unknowable?

Carl Sagan the US astronomer General said, before he died in the late 1990s, and is in his book Contact (made into a film staring Jody Foster) that if you took all the known galaxies and took just 1% of that figure as galaxies that could hold life,then took that figure and took just 1% of that as that number of stars that may have planets and 1% of that figure as planets that could hold life you end up with a figure of around 186,00 possible planets,,
We are not alone,,,

There must be some other form of life out there, whether its fully developed or just micro organisms is another thing, but there probably is life out there, we do not have the capabilities to travel all over space, we are limited to the distance we can travel within our galaxy, but there are other galaxies out there, which we have not discovered or visited,so you cannot rule out life form.

I think we'd be very presumptious & pompous to think that we could ever be the only thing out there. The Universe is a very small place considering how much is actually out there.... we are simply a grain of sand on the beach of existance. ☆

There ARE other beings out there, and they plan on invading your city in the next few months. ...but don't worry... they are harmless creatures. They call themselves women. Hard to understand lil things, but you'll find that eventually most of the men on our planet will fall in love with them and end up on yahoo answers asking other people for help in understanding their creature that they've hopelessly fallen in love with.

No we can't be alone in the universe I mean mathematically there are enough planets and life forms to be loads of parallel universes. Not that I believe it really but that must count for something...

life is some coincidental fluke? I don't believe that; we like on our little planet, which is in our little galaxy, which is in our little solar system, which is one of multi-trillions, there has to be life somewhere, a parallel universe, some other accidental fluke. we cant be alone.
