What are the three most important factors of where humans decided to live one thousand years ago?

One thousand years ago, humans primarily settled in areas with access to fresh water, which was essential for drinking, agriculture, and transportation. Fertile land for farming was another crucial factor, as it allowed for the cultivation of crops and the sustenance of larger populations. Additionally, safety from natural disasters and threats from other groups played a significant role, influencing settlements in defensible locations or areas with natural barriers.
