Now I stand to be corrected about this because this is just my own could be wrong opinion.
In Genesis when it says that God made man in his image,,I think it may well have been literally lets make man to looks like us (legs a head feet evrything even the genital thingy).
Now the teaching that it meant let man have intellect and feeling like God(s) (actually it is plural.(Probably from the polytheistic days of isreal?). That makes a point for God being like man and then we can understand the beleiver can understand the anger, jealousy, and quite frankly the evil nature of God this works well because God is the product of human imagination and man is quite limited as to what he can imagine God to be like. Thus assuming God is like man makes it easy to keep the people in fear of him and easier for the preistly class to explain.
