Excellent, you're proving my point. We don't have evidence of complexity of religion from the ancients (and yes, one could probably make the same argument about Judaism in Tanach. However, I don't think the same same argument can be said about Second Temple era Judaism, and that's still in times paralleling to some of the polytheistic religions I mentioned). My theory is that our seeing layers and layers of meaning stems from a mentality instilled in us from our abrahamic-monotheism-rooted culture. The want of deepness likely always existed everywhere - but that doesn't mean that such depths manifested in every religion. Because at the same time, not everyone had the energy or was interested in 'wasting' energy on going deeper. Some stories were just stories! I'm glad that you find deeper meaning in them (I think that reflects a certain positive thirst within mankind), but that doesn't mean that they were necessarily invented for that deeper meaning.The myth was written down in medieval times but the complicated meaning did not need to be written down anywhere. It is clear to anyone following this path today. It is not in isolation but interconnects with the mythology of the people created it. It connects with the archeology and the symbols we have. Something does not have to be written down to be true.
As I am welcome to mine, so too are you welcome to yours. I don't believe I have stated on this thread outright that you are wrong; only having questioned your views (I have always emphasized that this is a theory of mine, and here I am doing my best to defend it). I would expect the same courtesy, but I guess I expected too much.It is just not correct.
Have a good day.
