As stated by Death in the season 10 final, before there were God, Archangels, or even life there was The Darkness. So before God created anything else(Heaven, Earth, Purgatory, ect..) he had to defeat The Darkness, with the help of his Archangels. You have to understand that in the show, they always talk as though Archangels and Angles are two different species. They always call Archangels by Archangels and all other angels by just angels, no matter their rank.
