The climatic studies of the Arabian Peninsula showed a rainy climate in the central region 190-240,000 years ago and 75-130,000 years ago, which, in turn, led to the formation of several networks of rivers, valleys and vegetation that contributed to improving the living conditions of human groups, making Saffaqah the largest Acheulean site in the Arabian Peninsula, located at the confluence between the tributaries of Wadi Al-Batin and Wadi Al-Sahba.
The first hominins to leave Africa - whoever they were - carried with them oval- and pear-shaped hand axes used to pound and scrape food - a technology called Acheulean. The oldest tools found at Attirampakkam, which are more than 1 million years old, were crafted in this tradition.
