Civilisation is based on a surplus of food, which is generated by growing a plentitude of crops. Crops need water, and so do humans and animals they domesticate.
In a pocket of fertile land, with a river for fresh water supply, and access to the sea for fishing.
Early civilizations developed agriculture to produce food for their families. This involved cultivating crops such as wheat, barley, and rice, as well as domesticating animals for meat, milk, and labor. They also developed techniques for irrigation to ensure a steady supply of water for their crops.
The river valleys favored the rise of early civilizations because the rivers provided a continuous supply of water for farming and human consumption.
Usually a water source.

because they needed water
Civilisation needs a surplus of food as a precursor. Arable land and plentiful water gives a surplus.
Most ancient civilizations built their societies around rivers (ex: Tigris, Euphrates, Yellow, Nile). They did this because rivers are fresh water and supply water to drink as well as for irrigation (agriculture). Food and water supplies are a must for a civilization!

In order for early civilizations to develope they needed a good source of water. With water they could irrigate their crops and improve travel. If they did not have a solid source of water to develop farming early civilizations like the Egyptians(Nile River), Mesopotamians (Tigrus and Euphrates Rivers), or Indus river civilizations would not have survived.
