Your post seems result of a moment of depression. But the questions raised are the same as of those human beings who started thinking for the first time.
What is the life about?
What is the point?
But these questions may not be answered 'objectively' by any human being. Answers shall be colored with the beliefs, culture, knowledge, religion etc that the answering guy shall have.
I invite the visitors to respond on your thought provoking questions.
