It is attributed to Indian mathematicians.

Zero is itself a digit so the question does not really make sense. However, the non-zero digits are older than zero. For example, consider the Roman number system which had no zero.
The Mayas invented zero before it was introdiced to Europe. This allowed them to make complex calculations.
