The document discusses how ancient farmers along the Nile River learned to control its flooding and developed early astronomy and engineering. As the Nile flooded each year, depositing rich soil, settlements grew along its banks. However, floods were sometimes too large or small, harming crops. Over centuries, wise farmers noticed the floods correlated with star positions, allowing them to predict flooding and develop calendars. They also built canals, dykes and reservoirs to store and distribute water, establishing early engineering practices.
