The concept of god in the primal belief systems. Most of these primal religions have a creator god.
This god is too great, very powerful and too distant to be worshipped directly; whenever there is something extraordinary he is called upon (Exactly like today);
This god is believed to be all-seeing (A clue to one of the characteristics of the supreme being of our times?);
This god is unbound by time, unbound by place and has no end;
This god is compassionate, but unpredictable;
To get in touch with this god the earthlings needed intermediaries, because man could not get close to him (They needed sort of go-betweens/modems/interfaces like archangels, angels and messengers, as do believers of the day need. Any change since then? None!).
