Cooking makes tough meat easier to chew and digest and makes it last longer, by retarding spoilage, so it’s very likely that most of the time, maybe nearly all the time, most of the meat our ancestors ate for the last few hundred thousand years at least was butchered with stone tools and cooked in a fire.
How did humans make fire?
The main sources of ignition before humans appeared were lightning strikes. Our evidence of fire in the fossil record (in deep time, as we often refer to the long geological stretch of time before humans) is based mainly on the occurrence of charcoal.
Can we survive without fire?
Thus fire was limited to cooking, transportation and winters. But gradually everything was taken over by electricity. Today cars, trains, industries, computers, phones and all major gadgets run on electricity. So we can definitely survive without fire but not without heat.
Why did earlier people use fire?
Fire provided a source of warmth and lighting, protection from predators (especially at night), a way to create more advanced hunting tools, and a method for cooking food. These cultural advances allowed human geographic dispersal, cultural innovations, and changes to diet and behavior.
