It is my belief that cats, for one, have their own deities. I also believe that at least some of their deities enjoy live sacrifices and prolonged torture. I am distinctly a cat-person, mind you, but there's something about some cat behavior that seems best explained by this. Sure, part of it is the cats trying to teach us how to hunt. That doesn't cover everything, though.
More than a decade ago my housemate at the time and I had a pair of brothers from the same litter. We found a pile of entrails on the white bathroom carpet two days in a row. No hair, no blood, no bones. Just the entrails of something that must have been as large as a squirrel. It certainly didn't map to "teaching" at all. It stopped after we both talked to our cats about it. I said they could do whatever they liked, but they should keep it outdoors. What sort of strange ritual were the cats performing? I, for one, haven't the foggiest. I'm confident that it wasn't praying to Jesus, though. (Even though my wife says cats like Jesus -- anyone who can multiply fish like that has to okay in their book, right?)
Note that I'm talking specifically of the deities of the cats. This is entirely different than the human deities governing or pertaining to cats. Human deities may have a cat head or take a cat shape, however they are tuned to the human mind and spirit. Cat deities on the other hand are tuned to feline minds and spirits. That is to say, I suspect that even in ancient Egypt the cats did not worship Bast or any other human deity
It seems logical that cats, like most creatures capable of complex social interactions, probably have multiple deities. But what about the simpler souls? If we accept that amoebae have souls, (as I do), is it logical to expect them to also have multiple deities?
I suspect that the extent of the variation among the deities of a particular species is directly related to the number of ways that the species is capable of perceiving the world as well as the number of types of social interactions that are available.
Some things may only have a single possible deity available. Rocks? While they can form complex interactions with any number of things, on their own they are pretty boring. It seems logical that the deities of the rocks would be as boring.
If there is no distinguishing characteristic that separates two deities they are essentially the same. More than that, if there are no distinguishing characteristics between two souls they are essentially the same.
Is it possible that instead of having numerous distinct amoebae souls and deities there may be a single Spirit governing the aspects of the amoeba with no distinction between members or between souls and deities? Personally, I think it is possible. It certainly bears more research.
