I've never been and we can't possibly test it from this distance, so we don't know.
If you mean 'life in general' then, yes, probably. If you mean 'intelligent life' the odds are much lower but still not outside of possibility.
The Galaxy is freakin huge.
Wikipedia Entry quote:
"The main disk of the Milky Way Galaxy is about 80,000 to 100,000 light-years in diameter, about 250,000 to 300,000 light-years in circumference, and outside the Galactic core, about 1,000 light-years in thickness. It is composed of 200 to 400 billion stars [1]. As a guide to the relative physical scale of the Milky Way, if the galaxy were reduced to 130 km (80 mi) in diameter, the solar system would be a mere 2 mm (0.08 in) in width. The Galactic Halo extends out to 250,000 to 400,000 light-years in diameter. As detailed in the Structure section below, new discoveries indicate that the disk extends much farther than previously thought"

There is life throughout this galaxy, so we presume throughout other galaxies. The Milky Way Galaxy is over 100,000 light years across and contains hundreds of billions of stars. Andromeda Galaxy is 2.2 million light years away and is our nearest major galaxy. It is a shame that Humans will not survive as a species long enough to travel to other planets. 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. Your infantile,(in cosmic terms) dependence on god concepts does not bode well for you and neither does your penchant to breed beyond your planet's ability to sustain 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.

First question: absolutely no one knows. Other galaxies are SOOOO far aways that we know almost nothing about them. They are so far away that using current technology, for example, we could never see a single other planet there, and the likelihood of receiving an signals from anyone so far away is very remote. Most people who think about whether life in other worlds is possible focus on other stars in our galaxy.
Our galaxy has a diameter of about 100,000 light years and contains 200-400 billion stars.

well no one knows for sure if there is any other life out there. we asume there is because there is a few billion stars in our galaxy and there are more galaxies in the universe than there are grains of sand on all of the beaches in the entire world. for us to be the only star system that formed life would be such a low probability that its basically 0.

There is no difinative way to tell if there are other life forms in our galaxy besides the ones on our planet. But it would be very egotistical to assume that this is the only planet with life on it. We have found life to exist in many places. Under water. In the air. on the ground. under the ground. Deep in the earth's crust. there are bacteria that cant live in an oxygen enviroment. So the extremes are limited only by your imagination.
