The Religion of Ancient Egypt is great volume on the subject of ancient Egyptian relirious beliefs by the great British egyptologist, Flinders Petrie. Please see this passage for more: "Before dealing with the special varieties of the Egyptians' belief in gods, it is best to try to avoid a misunderstanding of their whole conception of the supernatural. The term god has come to tacitly imply to our minds such a highly specialised group of attributes, that we can hardly throw our ideas back into the more remote conceptions to which we also attach the same name. It is unfortunate that every other word for supernatural intelligences has become debased, so that we cannot well speak of demons, devils, ghosts, or fairies without implying a noxious or a trifling meaning, quite unsuited to the ancient deities that were so beneficent and powerful."
