This site has a strange premise and here I am going to explain it to you!
Angels are not created as angels.
And here's the process by which you become an angel;
1) Human dies
2) Human becomes a soul
3) Human's soul is judged
4) Soul is judged to be good
5) Soul is given form as an angel (Cherub, Seraph or Throne)
6) Angel keeps human name
7) As an angel you do your duty depending on rank
And here is the process for becoming an Archangel;
1) Archangel dies
2) Angel is selected to replace them
3) Angel chosen to replace the Archangel changes form to become stronger and more human in appearance (only two wings)
4) Angel takes the name of the Archangel they are replacing
