If we as humans are created beings likes angels, does that mean God breathed in angels also?
Good question.
Angels are eternal, and not created in Gods likeness.
Angels are Gods servants and messengers.
We are described as created out of the earth, into which God breathed life.
In essence our origin in from earth, where as angels are from heaven.
The emphasis of breathing life probably is there to ground us in our origins, from the earth,
not something great or precious or special, just plain and simple earth. And from this humble
origin God blessed us with life.
Lucifer or the morning star is described like this
11 All your pomp has been brought down to the grave, along with the noise of your harps;
maggots are spread out beneath you and worms cover you.
12 How you have fallen from heaven, O morning star, son of the dawn! You have been cast
down to the earth, you who once laid low the nations!
13 You said in your heart, "I will ascend to heaven; I will raise my throne above the stars of
God; I will sit enthroned on the mount of assembly, on the utmost heights of the sacred mountain.
14 I will ascend above the tops of the clouds; I will make myself like the Most High."
15 But you are brought down to the grave, to the depths of the pit.
Isa 14
