Which concept did early Greek thinkers use to move beyond strictly narrative accounts of the cosmos?

Answer

Geometry.

Ancient Greek astronomy represented a significant turning point because thinkers like Thales and Pythagoras began shifting the explanatory framework for the cosmos away from purely mythological or narrative accounts. They introduced abstract reasoning as a tool for understanding the heavens. Specifically, geometry became the preferred method through which these early thinkers attempted to describe and model the universe's operations, laying the groundwork for a more impersonal, mathematical understanding of celestial mechanics, rather than solely relying on stories of gods and heroes.
