We have no hard evidence at this time that there is life to be found anywhere else in either our solar system, or the rest of the universe. Still, as an astronomer, I think the chances are very good that life exists elsewhere.
Paleobiologists report that life on this planet may have arisen not once but several times when the Earth was very young, perhaps only a few hundred million years old. During this period, there were many frequent impacts with very large asteroids as the formation of the Earth was ending or the Moon was being formed, and each of these impacts would have incinerated any biological system then in existence.
The planet Mars very likely had lots of running water on its surface when it was very young, but lost it all once the atmosphere leaked away. But there could have been a period lasting over one billion years when bacteria like that on Earth could have formed. That's why we are now excited about looking for fossils of ancient martian bacteria on Mars. If we find them, that will mean that the conditions for evolving life, even just bacteria to start with, are fairly generous and we could expect lots of bacterial life in the universe given that a planet orbits its star at the right range of distances.
We now know that our solar system was formed in a way that is common to many stars. We have observed disks of matter orbiting young stars, and even old ones, that is probably dust and asteroidal material. We have even detected signs of planets orbiting several stars, though additional work is needed to firm up this as the only explanation for the data we have. See a previous question for more about this, and the archive about questions about Other Planetary Systems.
So, I think the chances are better than ever that there is life elsewhere in the universe. We still don't know how often evolution ends up with intelligent beings. This may be very rare considering the fickle conditions that had to occur on Earth for mammals and intelligence to become an important evolutionary skill. Dumb animals lasted billions of years on this planet before something like homo sapiens evolved! A universe filled with bacteria and dinosaurs could be the rule, not the exception.
