Odd choice of site to post this, as it is very quiet here.
In an infinite Universe there will be on infinite amount of life, in varying stages of evolution.
Galaxies older than ours will have had longer to evolve life.
Solar-systems within our own galaxy (further out at the edges) are also older and more likely to have intelligent life.
Navigating your own galaxy to find life is problematic, as your best bet is to go the long way, around the edges, where most life will be found (or even long-extinct life)
Have a play with the free program Celestia if you want to feel very, very small.
