Prehistoric people, our ancestors,created our living styles we just changed a few things as our brains
 became larger.

Wildfires are a cause of animals and prehistoric peoples migration. Wild fires would force
 the animals to migrate or just get out of the way. But these fires did help the prehistoric people in one way.
 The animals that couldn't get out of the way in time burned which left a delicious but burnt meal for prehistoric people. 
Since fires are such a scare to prehistoric man you would never think that they would make and use fires them
 selves, not wild fires though.

Humans have used fire for 250,000 years, we would know this because scientist have found hearths or remains 
of hearths. This is evidence that prehistoric people used fire intentionally. Hearths are used to contain a fire, to stop it
 from spreading these are usually in stone shaped circles. 
The hearths are also evidence that the fires weren't wild fires because hearth fires allow artifacts like bones to be closely analyzed for chemical changes because of the higher temperatures. From the analysis from the chemicals in the bones we can get a few hints that the first use was by humans more than 1,000,000 years ago.
More evidence that we used fire in different ways was discovered in the Swartlands in South Africa. Remains of prehistoric animals bones that were burnt. 
This could suggest that they learn't to cook their meat. But it is also a possibility that they did not make the fire themselves. I came to the suggestion that maybe the prehistoric people didn't light a fire or cook the animal at the time they simply dragged the animal back to the cave from the wildfire.
But fire to our ancestors was very important fire could give them
  • Cooked food which make it taste better
  • Killed parasites
  • Kept them warm throughout cold weather
  • provided light 
  • Kept predators away
  • And lastly made migrating from cold to warm weathers possibly for prehistoric people
