• Is this really the only way out of here?""It looks like someone\s left a trail of clues
• We can learn a lot about ourselves exploring deep underground caverns like this.""But what do they tell us about extra-terrestrials?
• Welcome to “the meeting place of the Jinns”.""This is about to get a whole lot spookier
• Today\s destination is bordered by the United Arab Emirates, Saudi Arabia and Yemen.""Shall we shed some light on this mysterious place?
