Answer:
the Indian subcontinent
The Vedic religion developed in the northwestern region of the Indian subcontinent during the early Vedic period (1500–1100 BCE), but has roots in the Eurasian Steppe Sintashta culture (2200–1800 BCE), the subsequent Central Asian Andronovo culture (2000–900 BCE), and the Indus Valley Civilisation (2600–1900 BCE).
