Are We the Only Intelligent Life in the Universe?

We know that here in our solar systems there aren't a lot of signs of life. We now think that almost every star out there has planets around it and a huge fraction of them have even Earth-like planets. And so with so many places that life could be out there in the universe, sometimes we wonder why haven't we found it already? Yeah, it's a very big question. One that would kind of determine our place in the universe.
