They aren’t actual human children. I promise you that. Even demons that are in a human body from birth have to grow into adults. You can’t fix what God didn’t create. These are creations of satan.
It’s generational. Like we are born from God. They are born from satan. Sounds crazy if you don’t know but it’s true. Think about the nephilim in the Bible. The fallen angels mated with human woman. The offspring were demonic giant cannibals. Funny too is that in biblical times they were called the Canaanites. (Cannibals?) When the flood killed most of them who were above ground they became the disembodied spirits that are demons. They’re still breeding today. They just aren’t giants. They manipulated dna.
Anything that God doesn’t create himself doesn’t have a soul like we do. Like clones for example. Soulless.
