Recall that divine Earth Mother figures...
These are from pre-agricultural periods and eventually disappear. Agriculture changes everything including religion, and it, according to the germs gun'n steel idea sets us all on a war footing. The Epic of Gilgamesh is just one of many examples. The big kings and the accumulation of large tracts of land are created by agriculture. These days we see parallels in the structuring of economies and mega corporations.
That is a grotesque caricature of the way the ancient peoples understood religion and spirituality - one that is, ironically, not too far from the popular caricature of the God of Israel as an abusive, genocidal patriarch.
Ok. Well, I think that large scale agriculture and humanity combine to make a warring society, and people begin to realize this is not good. The Caananites you mention are some of the most oppressed people of the ancient world, so its natural to guess that they are among the first to realize things are not going well with humanity.
figures were present in both the Mesopotamian and the Kanaanite cultural traditions; recall Inanna's descent into the underworld to rescue her husband (and related stories in the Kanaanite tradition), the worship of fertility and homeliness as an expression of humanity's feminine side - but, crucially, also recall how, in the reverse, the cult of Elohim/YHWH actively suppressed the worship of Ashera/Ashtoreth/Astarte in Biblical times,
You refer to the stories about Israel and the Canaanites, but archeology indicates that the Israelites are the Canaanites, spelled with k or not. The religion of Israel also retains fertility concepts and symbols such the pomegranite and almond branch.
how the priestesses of rival gods were systematically debased in Biblical texts as "prostitutes", and how the Bible elevates toxically masculine stereotypes into the sphere of the godly.
The biblical texts decry the pederasty of the temples. The stories also are against all of the asheras and baals, male and female. Most likely these asheras and baals are political centers, perhaps from foreign nations, but nobody knows what were the real objections. Maybe they were recruiting people for service in foreign armies. Perhaps there was a superstitious fear of them? You can't really tell me that you know. You've got some absolutist opinions about scripture that I can't get behind and that I don't think are supportable. We have the public Christian interpretation, the public Jewish interpretation, the archeological interpretations and also the unknown and forgotten interpretations.
