I think I have a good idea of how the devils came to be (Pure Speculation).

When the Biblical God first created humans, they were Adam and Lilith. Lilith didn't want to submit to God and Adam, so she was banished from the Garden of Eden. God then made Adam a new wife, Eve, who was submissive to Adam and God. You know how the rest of that story goes. Samael tricks Eve and Adam into eating the forbidden fruit (fruit of knowledge), then God cursed Samael and banished Adam and Eve from the Garden fo Eden.

I think I remember it was mentioned in the bible that Adam and Eve (and Lilith) were "made in God's image". That could mean that they had a portion of God's divine power within them. Perhaps they had the ability to do what God could (create beings, and Miracles), but on a smaller scale. But they didn't do so because they obeyed God and never did what he didn't ask them to do. When God banished Adam and Eve from the Garden of Eden, he stripped them of their "spark", and had them roam the Earth to eventually create humanity as we know it.

Now Lilith, over time she grew to hate God, changing her  "spark" from "of God (Holy)" to one that "opposes God (Demonic)". And for banishing her from the Garden of Eden, she  wanted to take revenge by becoming a demonic being who seduces humans to stray from God's teachings. She may have also taken her powers to a level where she could actually create demons/devils like how God creates Angels. She would eventually meet Lucifer after his rebellion against God, and the two would join forces to fight against God and his Angels. Lucifer would help Lilith take revenge against God, and Lilith would provide him his forces by creating the common devils (Soldiers), the 72 Pillars (Generals and Elite forces) and the Extra Demons (Served directly under the Satans). Thus they became the "Mother and Father" of Devils.
