I'm 100% sure the "Devil of the Earth" isn't literally a supernatural fallen angel as we portray him. From the images shown for the events involving Ymir, the humans of her time look pretty primitive by modern standards, probably no more advanced than the Greeks or Romans. Maybe the abilities of the person or people who bestowed Titan power unto Ymir were so advanced, the people of her time could only imagine it being the result of the supernatural.
