Yes, it is a good study point. May I say that in Job 38:4-7 we see a hint of the answer when God speaks to Job............. "Where were you when I laid the foundation of the earth? Tell Me, if you have understanding, who set its measurements? Since you know. Or who stretched the line on it? On what were its bases sunk? Or who laid its cornerstone, when the morning stars sang together and all the sons of God shouted for joy?" Most all translations say that "Sons of God" are the angels which implies that they were present at the creation.
