Who wrote the Vedas?

Answer 1

According to Hindu tradition, the Vedas are apauruṣeya"not of human agency", are supposed to have been directly revealed, and thus are called śruti ("what is heard"). Vedic mantras are recited at Hindu prayers, religious functions and other auspicious occasions. They were written down by inhabitants of Ancient India, but they were not of human creation or writing. They are the most ancient and sacred texts of Hinduism.
The Vedas are considered the earliest literary record of Indo-Aryan civilization, and the most sacred books of India. They are the original scriptures of Hindu teachings, and contain spiritual knowledge encompassing all aspects of our life. Vedic literature with its philosophical maxims has stood the test of time and is the highest religious authority for all sections of Hindus in particular and for mankind in general.

"Veda" means wisdom, knowledge or vision, and it manifests the language of the gods in human speech. The laws of the Vedas regulate the social, legal, domestic and religious customs of the Hindus to the present day. All the obligatory duties of the Hindus at birth, marriage, death etc. owe their allegiance to the Vedic ritual. They draw forth the thought of successive generation of thinkers, and so contain within it the different strata of thought.
