The Vedas are beginningless. Just as God is without a beginning, then his knowledge is also without a beginning. It may be revealed at a certain point in time to a specific person, but that does not mean that the Veda did not exist before. God’s knowledge is eternal because it’s God’s knowledge. The attributes of an eternal object are also eternal. That is why we are also eternal.  We also have no beginning. The soul is not created because it is one of the potencies of God.
