Building a Civilization from Stone and Fire

When he opened his eyes, the world was filled with only stones, beasts, and cold wind... Even fire doesn't exist. In this era, humans still don't know how to make fire, and even the crudest tools are immature. They are afraid of the dark night, afraid of thunder and fire, and afraid of all unknowns. They are completely wilderness lives. Start: Church tribe lights the first fire. Later: Forging the first truly usable spear. After that: sheds, grain storage, hunting formations, tool systems, fire protection, the earliest prototype of order... When thunder, fire and beasts dominate the land, he is the only one who can bring the light of civilization into the darkness.
