Question: how did early humans make use of stones during the prehistoric period?
Answer: start fires, hunt, bury their dead

Prehistoric technology is technology that predates recorded history. History is the study of the past using written records. Anything prior to the first written accounts of history is prehistoric, including earlier technologies. About 2.5 million years before writing was developed, technology began with the earliest hominids who used stone tools, which they may have used to start fires, hunt, and bury their dead.
