Who is the oldest of all the mathematician?

The title of the oldest known mathematician is often attributed to Thales of Miletus, who lived around 624–546 BCE. He is considered one of the first mathematicians in history and is credited with various geometric discoveries and theorems. However, the exact ages of ancient mathematicians are difficult to determine due to the lack of comprehensive historical records. Other notable early mathematicians include Pythagoras and Euclid, but Thales is generally recognized as one of the earliest figures in the field.
