If one day, watching TV, they interrupt the programs to inform you that a comet is coming on earth what would you do? Would you believe who discovered this comet? Would you doubt? Would you go to the one you love to save them? By now it happens more and more often to read news about dangerous comets or meteorites. What attention do you give to such news? Do they shake you or do you remain impassive?Have you ever known something important and tried to tell someone and not be believed? Sometimes certain things seem so strange and impossible to be true yet by the time you realize they are true it will be too late.
