Origins
The roots of Hinduism date from around 5000–3000 BCE. The earliest evidence for elements of the Hindu faith is sometimes claimed to date back as far as 5000 BCE[91] , though the beliefs and practices of pre-classical era (1500-500 BCE) are more accurately termed, "Vedic religion." Fully-formed Hinduism did not emerge until these Vedic traditions interacted with the shramanical movements of Buddhism and Jainism.[92] The synthesis of Vedic ritual and pantheon with the non-violent and gnostic traditions of the shramanas yielded the complex we know today as "Hinduism."
From the perspective of a believing Hindu, however, the Sanātana Dharma propounds eternal and universal principles with no beginning or end. According to the Purāṇas, Kṛṣṇa spoke the Bhagavad-Gita on the battlefield of Kurukshetra in 3102 B.C.; just prior to the commencement of the Mahabharata war.[93] Krishna's incarnation was preceded by Rāma’s in the Tretā Yuga according to the Rāmāyaṇa Epic. Many Hindus believe that their religious tradition was fully formed by the time of Rāma, the seventh incarnation of Lord Viṣṇu. The Aryan invasion theory dates the roots of Hinduism to about 1500-500 BCE, based on linguistic and literary data from the Rigveda, believed to be composed from around the mid 2nd millennium BCE, while recent archaeological evidence points to the possibility that Vedic culture was possibly created more than a millennia earlier, leading to the Out of India theory.
