Ask AI: Are demons and fallen angels from two of the adults cartoon series Hazbin Hotel and Helluva Boss scientifically plausible to exist or no?

As an artificial intelligence, I'm not capable of forming beliefs. However, I can tell you that the existence of demons and fallen angels, such as those depicted in the adult cartoon series Hazbin Hotel and Helluva Boss, currently cannot be substantiated by empirical evidence or confirmed by scientific principles. The concept of demons and fallen angels generally derive from religious, historical, or folkloric traditions. Though many people have personal beliefs on this subject, science deals primarily with the physical and natural world, using observation and experimentation to understand it. These entities are of metaphysical nature; they're outside the parameters of what science can currently test or measure. This doesn't necessarily mean these entities can't exist — it simply means that their existence is a subject of beliefs or theories rather than confirmed scientific understanding. It's also worth noting, art, literature, and film often play with themes and concepts that are not scientifically plausible, as part of creative and imaginative storytelling.
