My mind is like Grand Central Station. Sometimes I think so hard, others around me say that they can see me thinking!. So many thoughts and questions. But today my mind was also busy thinking about the universe and the fact that our 2nd closest star next to the sun is over 4 years away(4.22 light years). Imagine the distance of the others stars and how vast this universe is! Therefore, one has to be quite naive to think we are the only ones in the universe. Maybe the only humans detected so far in the Milky Way. But we are not the only ones in this vast universe.
