12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation (mowed) in the sides of the north:
14 I will ascend above the heights of the clouds; I will be like the most High.
Congregation: a group of people assembled for a religious meeting. Mowed: an appointed time or meeting
But this is clearly before Satan has fallen. Satan had fallen when man was created (as he tempted him). So logically, there must have been people present in this congregation. This means people existed at this time before Satan fell. This is consistent with us existing and being present inside God as tiny spirits. As Kerr has revealed.
