Which civilization survived the longest How long?

The ancient Egyptian civilization is often regarded as one of the longest-lasting civilizations, with its roots dating back to around 3100 BCE and lasting until the conquest by Alexander the great in 332 BCE, totaling approximately 2,800 years. This longevity is attributed to its stable agricultural practices, effective governance, and cultural continuity. Other long-lasting civilizations include the Chinese civilization, which has evolved for over 3,000 years, but Egypt is notable for its relatively uninterrupted history.
