Detailed explanation-1: -The first recorded zero appeared in Mesopotamia around 3 B.C. The Mayans invented it independently circa 4 A.D.

Detailed explanation-4: -Zero’s origins most likely date back to the “fertile crescent” of ancient Mesopotamia. Sumerian scribes used spaces to denote absences in number columns as early as 4, 000 years ago, but the first recorded use of a zero-like symbol dates to sometime around the third century B.C. in ancient Babylon.
