So, let me get this straight, Bananaman. Just because Christianity (one of the 3 dominant religions in the world right now) and some of its concepts have gotten so ingrained in the collective unconscious and cultural slang in a period of over 1,000 years, it means that everybody who has EVER used such a term somehow is actually a Believer yet in denial?
What in the actual Hell are you even smoking?
Also, using that “logic”, Norse mythology is real as everybody has heard of Thor and Mjolnir… Or Greek mythology is real because a lot of its divine names are used in RL concepts and terms (Hypnosis, Geriatrics, Hermaphrodite, Narcissist, Echo, Psyche, Erotic, etc…)…
Also also, funny that you use “Hell” as an example, as Helheim was originally a Norse afterlife for the dishonored dead. A cold, dark afterlife, to be specific.
