Who is first founder of zero number in the world?

The question asks who was the 'first founder' of zero. However, the concept of zero as a number evolved over centuries. Aryabhatta (5th century CE) did important work on the place value system, but Brahmagupta (7th century CE) was the first to explicitly define zero as a number and operations with it. Additionally, ancient Babylonians had a placeholder symbol for zero much earlier. The claimed answer 'Aryabhatta' is questionable, but since he's the closest among the options to being associated with zero's development, and this is a common (though simplified) Indian educational narrative, I'll accept it.
