Life in the space, other than the Earth?

I noticed a simillar question was posted 3 days ago, but mine is bit different. I am asking for the possibility of the life in the "whole universe", not just our solar system.

I have very little knowledge on the space study, so I may misuse some words. But I am sure you understand what I try to mean.

As you know, there are many, many galexies out there, which could take some billion light years or more to just get to there. We simply can not travel that far, because our technology has not been developed sophisticated enough.

Based on this fact, I think it is natural to imagine that there must be some lives (not the primitive ones like the becteria, etc.), close to the human. They may not have been evolved good enough just like us right now, but who knows if they are having the middle ages of their own right now.

This is what I think. Do you think, or can you give me a fact that there may be a high leved livings like us out there?

Where do you think they possibly be?
