What evidence should I use for Survival?

The Creation of Fire:

"I have a friend, he thought—I have a friend now. A hungry friend, but a good one. I have a friend named fire." Chapter 9, pg. 86

The Tool for Survival:

But there is a difference now, he thought—there really is a difference. I might be hit but I'm not done. When the light comes I'll start to rebuild. I still have the hatchet and that's all I had in the first place." Chapter 16, pg. 146
