When was the first symbol?

Answer 1

The first known symbols used by humans date back to prehistoric times, with evidence of symbolic expression found in the form of cave paintings and carvings. Some of the earliest symbols, such as those seen in the Blombos Cave in South Africa, are estimated to be around 75,000 years old. Additionally, the use of abstract symbols became more prominent with the development of writing systems, which began around 5,000 years ago in Mesopotamia and Egypt.
