I think the demons used to be angels thing is specifically because of Lucifer, he fell from heaven and became the devil and the devil is in charge of demons I suppose so demon = former angel. At least I assume that's how it came about, I don't know another way it would make sense than mixing it up with Lucifer, I think a lot of people probably just don't think about it super deep and that's what happens.
The whole satan being a fallen angel is another thing i cant find scriptural evidence for. But like, everyone believes it? I was taught that in church, but with no evidence. Im just so confused
