Hmmm made up names might work -- it would be cool if the game would randomly grab one from a list so that each time a new game is played, there would be a new set of religions. You can do that for units, so maybe there is hope there. If not, maybe a more generic name but less fantastical if you get my line of thought.
Was this what you were looking for? I don't know how else to help in finding god names/characteristics that aren't culturally linked, when all gods were culturally linked. The best I can do.
And perhaps that is where we are getting confused with Goddess. Goddess is not a female God (as opposed to god) -- do you see the difference? Goddess is not God but a god; the god is a woman because early man saw a woman as the fertility of nature and of man. When I say Goddess, it isn't some spin on Feminism but just how early man saw nature.
Still confused, I'm afraid. Sorry. :\ There's no evidence that prehistoric humanity saw woman or a woman as fertility, unless you discount thousands of lingams that still existed and were carbon-dated at the same time, and the fact that the female fertility figures like their counterparts were localized, and the fact that the fertility figures for both sexes could be meant by their cultures not as gods, but fetishes to bring fertility luck. Gods and goddesses of fertility exist, but no all encompassing God or Goddess. Monotheism didn't exist at that time. If you have the source evidence, again, I'm truly interested in reading it. Otherwise, it will look a little to some folks (not many, I agree, for most couldn't care less) like putting metal smelting in a game and declaring that it came before the discovery of fire. It won't hurt the game in any way, since fire and metal smelting in Civ context are a series of tech placemarkers that can be called anything, but it will make at least a few people wonder where this is coming from.
I'm not saying "You can't do this, you, you...you!"

It's your choice. I fully realize that. But attempting to convince me of something I've never heard except from Dianic witches, who are feminine monotheists, without any supporting source materials, won't work. Best to just do it the way you want.
If you want a wild read I suggest you pick up a whole series of books written by M.A.R. Barker -- start with the Golden Man. After you read his books, then we really can talk about world building and religions.
I'll keep that in mind, though I haven't read fantasy/scifi in ages. Just no time.

I was only wondering if you were looking for good books that might suggest Atlantean stuff, and wasn't recommending them over anyone else. Haven't read their work in a long time, either, but they're both out of copyright, and Gutenberg probably has some of each.
