Humans have been around for around 350,000 years, but it has only been a short time since they began to group together in what we call civilizations. In all of our history on this planet, humans have only civilized themselves for approximately 10,000 years thanks to the development of agriculture, animal husbandry, and eventually writing. Of the thousands of civilizations that have existed, most have disappeared. Few have remained in the same place they originated such as the Chinese or Egyptians, while most have died out. Many ancient civilizations existed throughout human history, but some lasted longer than you might believe.
