Flint, a form of quartz, creates sparks when struck against a mineral containing bits of iron, and was the main method of starting fire for hundreds of thousands of years.
It had long been accepted that Homo erectus, the dominant human species on Earth from about 2 million to about 500,000 years ago, knew how to control fire, such as blazes set by lightning strikes, but not how to start it.
Actually setting fire was thought to have been invented by later, more advanced species, such as Homo heidelbergensis or his descendant, the well-known Homo neanderthalensis.
But the sheer age of the Gesher Benot Ya'aqov site, plus the distinctive stone tools found alongside the burnt flint at the earliest layers, indicate that Homo erectus not only was the first human species to leave Africa, but the first to learn how to start fires as well."
1. Who lost it?
2. Why must we wait 500,000 years to find it again?
Interesting.

So homo erectus is responsible for man-made global warming!
How did they establish the age of the fire?
