One day my belly was full and I wasn't being chased by a large predator and feeling relaxed for a moment I lay out on this flat outcrop of rock and began to give some thought to how I came to exist. Nobody else had given this any thought yet, so I was ploughing some fertile ground. I thought some great omnipotent deity must have created everything, so I called this g.o.d. for short.
I had some extra food at that time and it would have gone off before too long so I decided to honor my g.o.d. and layed it out on my rocky outcrop, it was another layered topologicolly even rock so I called it a.l.t.e.r. for short. I was convinced in following days, that I was able to feed myself with less effort and I put this down to offering a sacrifice to my g.o.d. on his a.l.t.e.r.
When I told my friends and family about my success, they wanted to hear more and soon I did not have time to go out and hunt any more. Of course they would bring me presents of food and I did not have to, so this worked out fine. In the course of time, I wrote my story down, making it a bit more interesting as I retold it over time.
