Actually I believe the real devil is someone like alpacino in the devil's advocate he is a person not some king of mystical being with or without horns he is a person just like us only older like a very old person who doesn't age like a vampire, you can go on YouTube right now and search about the satanic music industry or entertainment industry in general and you will find the world's most famous celebrities literally admitting they sold their soul to the devil for wealth and fame by signing a contract a process which interestingly enough was shown in the Disney cartoon alaadin in which the poor thief signs the genie's contract and instantly becomes a rich prince and as we all know according to the Quran the devil is just a genie I think somehow there is a connection I don't know if any of that makes sense to you but like you I am just searching for the truth and I could be wrong, and as to your other point I don't believe there are multiple realities but I believe in one reality multiple perspectives but I would love to hear more about it from you if you would like to tell me
