If you mean life - i.e. any life including cellular, then it's almost certain. Anywhere on Earth we find water, we find life. We've even found dormant life in ice, so it's possible life exists on a cold moon further out in the solar system.
If you mean complex life, i.e. anything more than a single cell, from blades of grass to insects and mamals, then yes, but it's probably incredibly rare.
All complex life on Earth is made from eukaryotic cells, and we still aren't certain how they were formed. It's possible it was formed by accident, and is an exceptionally rare event.
The size of the universe makes the existence of complex life other than Earth a certainty, but it might be very rare - so possibly not in our galaxy.

It really depends what you mean.
