They rubbed stones really hard causing it to generate a spark. With continuous generating of a spark, they lit a piece of wood. Wood can catch fire really easily.

Is iron wood the toughest wood?

What wood sparks a lot while burning?
Wood that is damp tends to spark alot. I have burned wood to heat my house for years, and am very familiar with wood types, and I have not found that answer to be correct. Certain types of wood just spark a lot, I don't know why. Hedge is the hottest burning wood I know of and is also the worst offender in the spark category. It seems that any yellow colored wood is a bad sparker, such as hedge (aka osage orange) and black locust and mulberry. They spark a lot, burn hot, and are yellow colored wood. The best overall wood is white oak, as it splits fairly easy, and burns really hot, but not too hot like hedge (it will melt your grates) has almost no sparks and lasts a long time.

What things are needed for fire to burn?
Dry wood, fire, ect, oxygen, and a spark are things that are needed for fire to burn.

Fuel, an oxidizer, heat, and an ignition source.

What kind of heat energy is burning wood?
Burning wood is the process of converting chemical energy in the fuel into thermal energy. Heat transfer is the process of moving thermal energy from one object to another. There are different types oh heat transfer including radiation, conduction and convection. Basically, the wood burning is a spontaneous process, theoretically, but in order for the process to become under way something called the activation energy must be overcome, which means that an energy of that magnitude must be applied to the wood to get it burning (oxidising). This usually comes in the form of a spark or a flame from your lighter. So once you apply that activation energy from your lighter, the wood begins to burn, and the burning of the wood itself produces heat to propagate the process. So long as there is oxygen, fuel (such as wood or octane for example) and the initial spark, then you have fire!
Why does dry wood catch fire easily as compared to freshly cut branches of a tree?
A flame can only ignite dry materials. Wet materials, if the spark catches, brings more smoke than flame.
