Most Egyptian deities represent natural or social phenomena . The gods were generally said to be immanent in these phenomena — to be present within nature . The types of phenomena they represented include physical places and objects as well as abstract concepts and forces . The god Shu was the deification of all the world 's air ; the goddess Meretseger oversaw a limited region of the earth , the Theban Necropolis ; and the god Sia personified the abstract notion of perception . Major gods often had many roles and were involved in several types of phenomena . For instance , Khnum was the god of Elephantine Island in the midst of the Nile , the river that was essential to Egyptian civilization . He was credited with producing the annual Nile flood that fertilized the nation 's farmland . Perhaps as an outgrowth of this life @-@ giving function , he was said to create all living things , fashioning their bodies on a potter 's wheel . Gods could share the same role in nature ; Ra , Atum , Khepri , Horus , and other deities acted as sun gods . Despite their diverse functions , most gods had an overarching role in common : maintaining maat , the universal order that was a central principle of Egyptian religion and was itself personified as a goddess . But some deities represented disruption to maat . Most prominently , Apep was the force of chaos , constantly threatening to annihilate the order of the universe , and Set was an ambivalent member of divine society who could both fight disorder and foment it . Not all aspects of existence were seen as deities . Although many deities were connected with the Nile , no god personified it in the way that Ra personified the sun . Short @-@ lived phenomena , like rainbows or eclipses , were not represented by gods ; neither were elements like fire and water or many other components of the world .The roles of each deity were fluid , and each god could expand its nature to take on new characteristics . As a result , gods ' roles are difficult to categorize or define . But despite their flexibility , the gods had limited abilities and spheres of influence . Not even the creator god could reach beyond the boundaries of the cosmos that he created , and even Isis , though she was said to be the cleverest of the gods , was not omniscient . Richard H. Wilkinson , however , argues that some texts from the late New Kingdom suggest that , as beliefs about the god Amun evolved , he was thought to approach omniscience and omnipresence and to transcend the limits of the world in a way that other deities did not . The deities with the most limited and specialized domains are often called  minor divinities  or  demons  in modern writing , although there is no firm definition for these terms . Among these lesser deities , Egyptologist Claude Traunecker draws a distinction between genies  — specialized patron spirits of certain places , objects , or activities , such as the sea or marsh god Wadj @-@ Wer and the harvest goddess Renenutet — and demons , who have a more dangerous character . Many demons are hostile , causing illness and other troubles among humans . Their power can also be protective ; they may guard certain places in the Duat , the realm of the dead , or advise and watch over humans . Egyptians believed the landscape was full of these unpredictable divine powers . Demons often act as servants and messengers to the greater gods , but their position in the hierarchy is not fixed . The protective deities Bes and Taweret originally had minor , demon @-@ like roles , but over time they came to be credited with great influence . fill in the blank  :   Most Egyptian deities represent __________________ or social phenomena .
