The fact that no authenticated firepits predate the first known appearance of Homo sapiens some 2,00,000 years ago indicates that it was impossible to control the use of fire without a large brain such as Homo sapiens has. Since Homo sapiens did not exist 4, 65, 000 years ago, a 4,65,000-year-old deposit that has been found consisting of charcoal and burnt bones cannot, therefore, be evidence that firepits existed considerably earlier than 2,00,000 years ago.
