Final answer:
The Fertile Crescent was the first place where humans formed a complex society due to favorable agricultural conditions, abundant food resources, and trade and cultural exchange.
Step-by-step explanation:
The Fertile Crescent was the first place on the planet where humans formed a complex society due to several factors:
It provided a favorable environment for agriculture with its rich soil and access to water from rivers like the Tigris and Euphrates. This allowed people to grow crops and establish permanent settlements.
The region had a variety of nutritious staple crops like wheat and barley, as well as key animal species like goats, sheep, and cows that were native to the area. This abundance of food resources supported the growth of a stable food supply.
The Fertile Crescent was also a hub for trade and cultural exchange, connecting different civilizations and facilitating the exchange of goods, ideas, and technology.
