The Vedas are a collection of religious texts that form the foundation of Hindu theology. Hindus believe that the Vedas texts are of divine origin and the term śruti ("what is heard") refers to this.The Hindu belief that the cosmos is eternal; was not created and will always exist, also applies to the Hindu view of the Vedas.The great epics of Ramayana and Mahabharata are intricately woven with Vedic naked eye astronomy based calendar.
Though much of the material has been lost, currently four Vedas and vedangas consisting of Brahmana’s, Aranayakas, Upanishads and sutras’ are available.But the Indus people (7000 BC- 1300 BC) spoke a language which is still hardly known. Carbon dating calculations proves the Indus Valley period.So the mistake could only be about the date of the migration.Hinduism places very little importance on criticism of other religions because Hindus believe that the path to God transcends all human thought.In this respect, a Hindu would not consider Buddhism or Catholicism to be wrong, only different.The geographical information given in the Rigveda changes from the beginning of the book to the end in a sequence supporting a migration from the northwest. The migration derived from the Rigveda cannot be dated back before Indus Valley civilization. The language spoken by the present people there is a Indo-Aryan (Sanskrit) derived language.
