G-d told Moshe to answer this question himself. Honor your parents. With these answers the angels were appeased. The Maharal explains that there is a paradox. The Torah is perfect and eternal.
Man is temporary.
This was the question of the angels. Moshe of all people was able to answer them, because Moshe, more than all people, had spiritually elevated himself to such a high degree that he could talk face to face with G-d. Yet he was still a human. When the angels saw to what degree a human could elevate himself, the paradox was resolved. G-d does not expect perfection from us.
