I think this is fascinating. Archaeologists have found the earliest known instance of human-created fire, in the village of Barnham in England, which they have determined occurred 400,000 years ago. This pushes the origin of human fire-making back by more than 350,000 years.

This is a pretty extensive article, delving into how they propose this site is so old and how they know the evidence of fire is human in origin.
