Yes it is Earth, of course! We live in Earth, we call it World, we love it! We want to make our beloved Earth or World a truly lovely place to live our lives. We want to make it a happy destination of the ETs (don't know, if they exist somewhere in the universe)! We hope that our World will be a lovely place someday, there will be no violence, no crime, and no jealousy! There will be only love and respect for the fellow people oneday, although I don't have any idea when all that will happen! No war, no crusade, no earthquake or tsunami! No negative things at all! In my dream I can see that will happen oneday and that day is not far away!
