Ultimate question..!!

Hi superdhruv. It's a really difficult question. For me the ultimate question is "Why we are here? What's our purpose in life?" Is it only that we have to grow up, have children, then have grand-children and eventually die? Or there is something more behind our existence? Or do we really need to have purpose in our lives? Till now I don't have an answer. Or no, it's not right to say that I don't have an answer but at different periods of my life I had different answers. So what do you think about it? :)
