Around what year was Democritus believed to have been born?

Democritus is believed to have been born around 460 BC, marking a significant point in the history of philosophy and science. He is often recognized for his formulation of an atomic theory of the universe, proposing that everything is composed of small, indivisible particles he called "atoms." This philosophical idea laid essential groundwork for later scientific discovery and exploration into the nature of matter. Understanding the timeline of his birth helps contextualize his contributions and the subsequent development of philosophical thought in ancient Greece. Other years listed do not align with historical accounts of when Democritus would have lived, further reinforcing the accuracy of 460 BC as the correct answer.
