<human>:  What is the best way to start a fire without matches?
<bot>: The best way to start a fire without matches is to use a flint and steel. To use a flint and steel, you will need a flint, steel, and some kind of tinder to help ignite the spark that is created by the flint striking the steel. To create the spark, hold the steel in one hand and strike it with the flint in the other. As you strike, the steel should create sparks that will ignite the tinder, allowing you to begin a fire.
