 Pre-historic Vietnam was home to some of the world's earliest civilizations and societies—making them one of the world's first people who practiced agriculture.The Red River valley formed a natural geographic and economic unit, bounded to the north and west by mountains and jungles, to the east by the sea and to the south by the Red River Delta.The need to have a single authority to prevent floods of the Red River, to cooperate in constructing hydraulic systems, trade exchange, and to fight invaders, led to the creation of the first mythology Vietnamese states approximately 2879 BC.
