Human settlements began when early humans started settling down in one place to grow food after discovering that seeds they dropped would grow into plants. They chose sites that provided key resources like good farmland, fresh water, building materials, fuel sources, shelter, and protection. Over many years, more people settled in these areas and some settlements grew larger and larger, developing into villages, towns, and eventually cities as populations increased and more services were needed. Early settlers prioritized defense, farmland, water supply, building materials, and shelter when choosing where to establish permanent settlements.
