 Support for this idea mostly exists among Indian scholars of Hindu religion and the history and archaeology of India, and has no support in mainstream scholarship.The standard view on the origins of the Indo-Aryans is the Indo-Aryan migration theory, which states that they entered north-western India at about 1500 BCE.The Puranic chronology, the timeline of events in ancient Indian history as narrated in the Mahabaratha, the Ramayana, and the Puranas, envisions a much older chronology for the Vedic culture.
