WHen did people develop the concept of numbers?

The concept of numbers likely emerged around 40,000 years ago when early humans began using tally marks and simple counting methods to quantify objects, such as animals or food sources. The development of more sophisticated numerical systems occurred around 5,000 to 3,000 BCE, with ancient civilizations like the Sumerians and Egyptians creating written numeral systems for trade, astronomy, and record-keeping. This evolution laid the foundation for mathematics as we know it today.
