RELAY 1: FIRE
The First Infrastructure
Fire represents humanity's first infrastructure achievement. The controlled use of fire transformed human capability, enabling warmth, protection, food preparation, and tool-making. Fire was the foundation upon which all subsequent infrastructure was built.
Before fire, humans were constrained by the natural environment. After fire, humans could extend their presence into new territories, modify their environment, and accumulate knowledge across generations through cooking, which improved nutrition and enabled brain development.
Fire infrastructure included the hearth, the gathering place, and the transmission of knowledge about fire-making and fire-tending. This was humanity's first shared infrastructure system.

HISTORICAL SIGNIFICANCE
Timeline: Approximately 400,000 to 1 million years ago, depending on the definition of "controlled" fire use.
Impact: Fire enabled human migration to colder climates, improved nutrition through cooking, enabled tool-making, and created the first shared infrastructure systems around hearths and gathering places.
Legacy: Fire remains central to human civilization. From fireplaces to power plants, from cooking to industrial processes, fire infrastructure continues to shape human society.
