Mother goddesses are just as silly a notion as father gods. If a revival of the myths of these cults gives woman emotional satisfaction, it does so at the price of obscuring the real conditions of life. This is why they were invented in the first place.
For millennia, men have enslaved women and attempted to appropriate female creative power, re-casting themselves as gods and creators. This assault continues today in the forms of ruthless wealth and mineral extraction, genetic engineering, mass surveillance, and war mongering.
The gods do not need sacrifices, so what might one do to please them? Acquire wisdom, it seems to me, and do all the good in one's power to those humans who deserve it.
The gods, as they are beneficent, if they find anyone who is healthy and whole and unscarred by vice, will send him away, surely, after crowning him, not with golden crowns, but with all sorts of blessings.
I've always loved the idea of mythologies linked to or underlying everyday life, like the kami gods of Shintoism, where every rock, tree and stream has its own little god associated with it.
Revenge, lust, ambition, pride, and self-will are too often exalted as the gods of man's idolatry; while holiness, peace, contentment, and humility are viewed as unworthy of a serious thought.
