The Fourth Millennium

It's New Year... 2999... The world has been devastated by a series of man-made as well as natural disasters. Only two land masses survive. Two completely separate worlds sharing the same planet. They both exist in almost complete ignorance of one another, until... A hundred years from now, we'll all be dead. A hundred years ago, we didn't exist. Time is precious; it only lasts while it happens. Beyond the 'here and now', time is gone; forever. This is not because we only live for 'the moment'. Times have changed. Things have changed. Everything has changed. The year is 2999. Today is the last day of the year, New Year's Eve, 31st December. Tomorrow will be not only the start of a new year, not only of a new century, but also of a new millennium. The start of the fourth millennium. That's three behind us already. Doesn't time fly? But what of the three thousand years that have passed? Three thousand years since what? Have there only been three thousand years since the beginning of time? Does anyone know? Does anyone care? No-one will tell us...
