Are we alone?

Loneliness is a feeling that no one would want to experience, and with a world with over seven billion people I can say, no, we are not alone. Thinking outside our planet, we do not know of any aliens, but I would not be surprised if there is an another place that has it's own life form. The universe is bigger than we can possibly imagine and there is every possibility of another planet contiaining life. Our planet it self there are over seven billion people and especially in a place like India it is impossible to be alone or even feel alone. I as a person feel very thankful for all the things that life has given me. I have a family and a home where I can go anytime and not be alone. I am looking around me right now and I can see five people, and most of the people in the world are always with one person or another, then how can we say that we are alone?
