Everything attains its name from something

What's a bush when it has no trees or shrubs? What's an ocean when it has no water or sharks? What's a house when it has no people or a family? What's hunger when some people look for medicines to make them hungry? Moreover, would the world be the world if there were no one on earth? Would a woman be called a wife if not married? I think everything on earth depends on something else to attain its name and recognition. Moreover, you wouldn't be called a husband if you married none, would you?
