I was looking at a lot of older religious art works since I'm in an art class or whatever and noticed that all religions, every last one of them had some depiction of the sun as being holy. The sun of god? Is god in fact the sun? I believe so. It's the creator of life it watches over us, all that good shit.
There's definitely patterns to how a culture's religions develop as the society develops. They tend to start with sun gods and animal spirits for aid in hunting, then as the people develop farming techniques they tend to invent new agricultural gods - Gods that die and rise again like the crops do and river gods that bring the floods that the farmers rely on for a successful harvest. Myths like that of Isis and Osiris or Jesus are typical examples as is the Great Flood legend of Noah (or Nuh, as he was known in the Epic of Gilgamesh, thousands of years before Christianity). Basically when faced with anything that caused people anxiety and felt out of our control, the solution was to invent a god, give it a personality and rules to follow, and thereby satisfy our mind's insatiable urge to feel in control. To feel that things around us fit into patterns that we understand and can predict the outcome of. As a species, our greatest fear is chaos. We really, really don't like it.
