Why are we looking for exoplanets? 

We can't live on them considering the distance alone, so what are the current goals in the exoplanet search? Just to learn about the universe?

Being able to get a better handle on number, location, size, and make-up of expolanets is fundamental for a number of reasons.  It gives us a much better idea of how common other life might be in the universe.  It gives us perspective on how 'special' the Earth is.  It allows us to better understand solar system formation processes.  And, perhaps most importantly of all, we find out something we didn't know before.
