What was a god? A focus of belief. If people believed, a god began to grow. Feebly at first, but if the swamp taught anything, it taught patience. Anything could be the focus of a god. A handful of feathers with a red ribbon around them, a hat and coat on a couple of sticks…anything. Because when all people had was practically nothing, then anything could be almost everything.
