Recall (from Nature’s Instant Bread Dough), that the Wild Yeast and Bacteria found in flour reanimate once they get wet. Spontaneous fermentation of the flour begins.

Flour contains Enzymes that pre-digest the starch molecules, similar to the way Enzymes in saliva help pre-digest the food you’re chewing so more nutrients are available to your body. In any flour/water mixture, Enzymes break down flour into smaller molecules of sugar. These sugars are quick food for the Yeast and Bacteria microbes.
