You know... I don't buy into "Celestial Father" and "Earth Mother". Both may be represented by a male or a female deity. To the ancient Egyptians, the Sky were a goddess - Nuth. In some myths, Tiamat was goddess of the Sky and the Ocean both.

I think that the identification of Earth = female is yet another tool of the oppressors of women. Humans use the earth, period. Some of us are just more nice about it than others - those who believe in sustainability - but still. All this "Mother Earth" stuff don't change it. Nobody 'uses' the Sky, though. The Sky symbolize achievement, peak, striving. See my point?

To me, there is a god and a goddess to everything.
