Creation of souls

Hi EA! When you channeled Khan and he mentioned he incarnated himself as a middle eastern boy who got himself killed in a car accident, was the soul in that boy a brand new unique soul created by Khan, effectively making Khan an oversoul who can create new souls and unique conscious beings, or was the soul in the boy Khan himself? If answer is former, does that explain how most of the non starseed souls on earth are created? By high density beings like Khan acting as oversouls?
