Yes. This creation Earth has living beings in it. The most intelligent creature is the human being. The life given to him is a gift. There are so many mystries, which happen in your Life which are actually not answerable and I believe, getting helpless at some situations, why can't we get time back in our Life, why can't we surely know the future, who make Luck in your Life and why everybody in this world is not having the same kind of Luck.. are few such questions which can never be answered.
