History
It used to be that no human being owns the earth. Not even the first man, Adam, though he was instructed to beautify the earth . He was a sojourner and throughout history every generation sojourned the earth. Some may have stayed longer in one place at a time but still, they always moved. It is only at this day and age that people almost did not move at all, primarily because the world is getting full, and the place where they stay, they paid for. How did it happen? How did the estate come to be? How did one own one? Here is one of the sources of history.
