1. It is difficult to burn a wet paper because it contains water. A lot of heat is required to evaporate this water( to dry the paper). Only After the water is completely removed and the paper is totally dry, the heat is used to reach the ignition point of the paper from where it then starts to burn.
2. IT ALLOWED HUMANS TO MIGRATE. Permanent human communities can be found on six of the Earth’s seven continents, and that’s partly thanks to fire. For early humans, harnessing fire was more of a way to cook food than provide heat. Research has shown that our hominid ancestors first learned to harness natural fires almost 1 million years ago, but they only started consistently managing and maintaining fires of their own in hearths about 400,000 years back. Sixty to seventy thousand years ago, around the same time humans left Africa and started migrating to new continents, humans began using tools to make fires. In addition to acting as a heat source, fire would have also allowed migrating humans to protect themselves from predators and extend the shelf life of their food supplies.
