Who found zero?

Hint: In order to solve this question let me give you the information that the zero was found in India and it is the major information that the zero is found by the great mathematician and astronomer Aryabhatta but this information is not fully correct firstly the Aryabhatta used the zero in decimal system.

Complete answer:
For solving this question let me tell you that there is major information regarding that the zero is found by Aryabhatta but the zero is not found by the Aryabhatta is is only used by him in the decimal system it was found by the Brahmagupta.
"Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628," said Gobets. He developed a symbol for zero: a dot underneath numbers.
Some scholars assert that the Babylonian concept wove its way down to India, but others, including those at the Zero Project, give Indians credit for developing numerical zero independently. "We are of the view that in ancient India are found numerous so-called 'cultural antecedents' that make it plausible that the mathematical zero digit was invented there," said Gobets, whose organization is composed of academics and graduate students devoted to studying the development of zero in India.

Note: While solving these types of questions let me tell you that the invention of zero and its implementation is done by two different people that are invented by brahmagupta and implementation by aryabhatta so this information should be kept in mind.
