00:00before pyramids before palaces there was mud thick fertile mud spread by rivers that rose
00:07and fell with the seasons the rivers that fed the wheat also salted the earth and when the
00:13soil turned white the world's first civilization began to die long before cities hunter gatherers
00:20roamed these floodplains every spring the rivers overflowed flooding fields then retreating to
00:26leave dark rich silt behind this is the story of how humanity learned to control nature
00:32and how that control turned against them it was a rhythm older than memory
00:37then came an idea what if water could be guided
