"In many languages gender is assigned to furniture. Is that a clue of some kind?"

Yes, actually. It is. Very specific clues to that culture's beliefs regarding gender, and how they associate material things with gender roles.

"It's just an extension of nature to give gender specifics to other items. To call the moon female is a step of logic."

That's very funny, but I don't think it was intended to be. Thanks for proving my point.
