Are we alone in universe..?

The universe is vast. You and I or anyone else cannot imagine how huge it is. There are billions of galaxies out there each containing billions of billions of stars. Even if 1% of all these stars have a planetary system like our solar system, that means millions of cases and the chances are pretty huge for another life form, be it intelligent or not. It is almost harder to think that we are the only one. It is naive to think that since we haven't found any other intelligent life near us then there is no life form in the universe. The nearest star to our earth is 4 light years away. That means the image we see of that start is from 4 years ago, that is how far it is and that is just the closest start.
