Some remarks
In short
I think God of All Creation need to be rebalanced, and that some other pantheons need a buff :
Goddess of Fertility, Goddess of Festivals, Goddess of Love, Goddess of Renewal, Goddess of Springtime, and maybe Goddess of the Hunt.
What do you think of it ?
In details
Ancestor Worship
+1 Faith for every 4 Citizens in a city; +1 Culture and +1 Faith from Councils.
Good. Produce a sufficient amount of faith to have a religion. Give some culture for early game, and a lot of faith for late game.
Earth Mother
+1 Faith and +1 Gold from Mines on improved resources, and +2 Production from Monuments.
Average. If you have some luck, it may be quite good, especially in early game. Nothing scale with eras so it become a little useless in late game.
God of Commerce
+1 Faith for every 20 Gold produced by owned cities; +2 Faith and +2 Science Gold in Cities with a City Connection.
Good. Probably better for AI than for players. The +2
science gold per cities is always cool.
God of Craftsmen
+1 Faith and +1 Gold from Quarries and Stone Works, and +2 Production in cities with a Specialist.
Average. If you have some luck, it may be quite good, especially in early game. Nothing scale with eras so it become a little useless in late game.
God of All Creation
+3 Faith in Capital; +1 Culture and +1 Happiness for every Pantheon ever founded (including this one).
Overpowered, or Good. Please change it to "+3 faith, +8(or 7) Culture, +8(or 7) Happiness", or at least to "every Pantheon ever founded (including this one) by known civilisation". Because on huge maps, its just too good. And if you don't exand a lot, the +3 faith is not so far to the amount of faith produced by others pantheons, so taking it does not really reduce your chances to have a religion.
God of the Expanse
+25% faster border growth, and gain 20 Faith every time a city expands its borders. Bonus scales with Gamespeed.
Average. I don't like it, because it does not give any non-faith yields. But it is not so bad.
God of the Open Sky
+1 Culture for every 3 featureless Plains or Grassland tiles (without hills or features) worked by a City; +1 Faith and +1 Gold from Pastures.
Average. If you have some luck, it may be quite good, especially in early game. The culture for featurless Plain or Grassland may be difficult to have, but it can be quite good even in late game.
God of the Sea
+1 Faith and +1 Production from Fishing Boats and Atolls; +3 Food in coastal Cities.
Average. If you have some luck, it may be quite excellent, especially in early game. The main problem is that you need to reveal fish before knowing if this pantheon will be good or not.
God of the Stars and Sky
+2 Faith, +2 Production, and +2 Culture from Tundra tiles with improved resources.
Good. It can transform a bad start into a good one.
God of War
+50% increase in City Ranged Combat Strength, and gain Faith if you win a battle.
Good. It may be difficult to found a religion with, but if you manage to do so, it will give you a lot of faith.
God-King
+1 Culture, +1 Faith, +1 Gold, and +1 Science for every 6 Followers.
Good. Maybe overpowered. But I like the idea of "if you convert everybody to your religion, you almost won the game". And this pantheon do exactly that.
Goddess of Beauty
+3 Faith and +1 Culture from World Wonders. +15% Production of Pre-Renaissance Wonders.
Average. I don't like it. It's difficult to found a religion with it, especially at higther difficulry level. But at least, if you fail to build wonders, AIs will convert you to their religion and you will have a usefull pantheon instead.
Goddess of Fertility
+1 Food and +1 Faith from Shrines and Wells, and 15% faster Growth Rate.
Bad. Food is no longer a no-brainer. It does not gives a lot of faith, so its difficult to have a pantheon with it. Moreover, it boost Wells and not Water Mill. So either add Water Mill to the list of buildings, either boost the bonuses to make this pantheon be a "I have no cities next to rivers" pantheon.
Goddess of Festivals
+1 Faith, +1 Culture and +1 Gold for every unique Luxury Resource you control.
Bad. Usually, there is more than 6xLuxury Followers of your Pantheon, and God-King gives the same yields, plus science. And if you will have less than 6xLuxury Followers, there is other pantheons for you, for example God of All Creations... A proposition : +3 Faith, +1 Culture, +1 Gold, +1 Toursim for every unique Luxury Resource you control.
Goddess of Love
Gain 10 Faith and 10 Golden Age Points every time a Citizen is born. Bonus scales with Era and Gamespeed.
Bad. Or at least, it seems bad. I've never tested it, but I don't see when it would be good. Maybe add "10% food carried afte birth" ?
Goddess of Nature
+1 Faith and +1 Culture for every 2 Mountains within 3 tiles of a City, and Natural Wonders gain +3 Faith and +2 Culture.
Good. And even overpowered with some mapscripts.
Goddess of Protection
+10 HP healed per turn in friendly territory; +1 Faith and +1 Culture from Palace, Walls and Barracks.
Good. Gives early culture. Now that the barracks give science, building it quickly in every cities is not stupid.
Goddess of Purity
+1 Faith and +1 Food from Oases, Lakes, and Marshes; +1 Happiness from Cities on rivers.
Average. If you have some luck, it may be quite good, especially in early game. The Happiness is always usefull in late game.
Goddess of Renewal
+1 Faith and +1 Culture for every 2 Jungle or 2 Forest tiles worked by a City; +1 Science and +1 Faith from Herbalists.
Bad. It was overpowered when it was "Every 3 jungle and forest within 3 tiles of a City". Before lambermills, you usually have better tiles to work than forest and jungles. Maybe : +1 Faith and +1 Culture for every Jungle or Forest without ressource (and +1 Science and +1 Faith from Herbalists).
Goddess of Springtime
+1 Faith and +1 Culture from Plantations, and +2 Gold from Markets.
Bad Both Plantations and markets came in late ancient era, and plantation on jungle need iron working to be done. So at least add +1 (or even +2) Faith to the Market.
Goddess of the Hunt
+1 Faith, +1 Food and +1 Culture from Camps.
Weak Not bad. I would not be against a +1 Gold to Camps, but it is not needed.
Goddess of Wisdom
+1 Faith for every 10 Science per turn. +1 Science and +1 Faith in every City.
Average Globaly weaker than God of Commerce, but it does not need a city connection, so not strictly weaker. Science per city is always cool.
Spirit of the Desert
+2 Faith, +2 Food and +2 Gold from Desert tiles with Improved resources.
Good. It can transform a bad start into a good one.
