[Dark Souls] How could humanity thrive in the dark?

Apparently, humans are creatures of the dark, and the dark age would be the age of men....
But how could humanity survive and build a civilization without the sun and fire? What kind of humans would they be?

Different people have different interpretations, but IMO:

The Age of Dark isn't an age without a sun, nor an age without fire. It's an age without "Fire" (capital eff), not fire (lower case f). "Fire" (capital eff) in this instance is the primordial Fire, the power of the Gods, which is why the Age of Fire is also called the Age of the Gods. "Dark" in the Age of Dark is not darkness, like the absence of light, but the absence of Fire, the absence of Gods. Humans were created by the Furtive Pygmy, born from the Dark Soul; the "Age of Dark" is so named *for us*, not for the lighting conditions, which is why the Age of Dark is also sometimes called "The Age of Humanity" in canon.

Dark is Dark, Dark is not darkness, Dark is humanity. Fire is Fire, Fire is not fire, Fire is Gods. Age of Fire is the Age of Gods, Age of Dark is the Age of Humans. When the flames of the Fire fade, the Gods have died, and humans inherit the Earth.
