It has the same amount of water as 1000 years ago. Unless this water has been taken off the earth in a spaceship, it will always be on earth, some of it in gaseous for, some in ice, and some in water. Most of the earth's water is non-potable (meaning you can't drink it its not clean). Water is always recycled, for instance, the water you drink today, could also have been drunk by a dinosoar, then peed out. The water would be recycled over time, with all the bad things coming out when it evaporates, then it rains back to the earth as pure clean water.
