It is not even clear where exactly Aryabhata was born. It seems the main thought is that he is from aśmaka, in India, but there is debate about where exactly that is. He apparently "called himself a native of Kusumapura or Pataliputra (present day Patna, Bihar)." But others think he may have been from a redion "between the Narmada and Godavari rivers in central India." So, there is that.
