Exactly Vedas have no Orgin.. good you this .... Supersoul - Supreme Lord... Soul - us,.. and Vedas are eternal. It is very high concept.
However Shri Vyasadev Compiled them into four Parts to make it more understandable and then came the Upanishads and Purans to make the Vedas further more understandable .....
Let me myself tell you ... It is the same authour - Shri Krishna Dvaipayana Vyas who compiled Vedas under the instruction of His Guru Shri Narada Muni, wrote Shrimad Bhagawatam, and at the end of it He mentions, Shrimad Bhagwatam is the JUICE of Vedas.
