 Babylonia was an ancient Mesopotamian state comprising of modern Iraq, Syria, and Egypt. The capital city, Babylon, was about 60 miles from modern Baghdad. Babylonians offered an early intuition on the infinite process. This is different from the base 10 or the decimal number system that we use today. Babylonian mathematics recorded their research and observations on clay tablets called cuneiforms. This is a famous cuneiform that shows that the diagonal of a square is root 2 times its side. They were also able to define other numbers with potentially infinite precision, like the length of the year, or even represent the value of pi, fast forward to 300 BC.
