There is a description of a war in Heaven.
Michael and his angels fought against the dragon and his
angels.
If nobody existed before birth, how could that be?
Angels are not human. You do not die and become an angel. No more than a duck dies and becomes a robin.
The battles in heaven were between the arch angels, (mike and his crew) and Satan’s gang.
We are just different species...so to speak.
Dan
sorry to break it to you but angels were NEVER people
and people NEVER “become” angels.
that is just plain bad theology.
