Title: Jordan
Content:   The oldest known evidence of hominid habitation in Jordan dates back at least 200,000 years. Jordan is rich in Paleolithic remains (up to 20,000 years old) due to its location within the Levant where expansions of hominids out of Africa converged. Past lakeshore environments attracted different hominids, and several remains of tools have been found from this period. Scientists have found the world's oldest known evidence of bread-making in a 14,500 year-old Natufian site in Jordan's northeastern desert. A transition from hunter-gatherer culture to establishing populous agricultural villages occurred during the Neolithic period (10,000–4,500 BC). 'Ain Ghazal, one such village located at a site in the east of present-day Amman, is one of the largest known prehistoric settlements

Title: Israel
Content:  The oldest evidence of early humans in the territory of modern Israel, dating to 1.5 million years ago, was found in Ubeidiya near the Sea of Galilee. Other notable Paleolithic sites include the caves Tabun, Qesem and Manot. The oldest fossils of anatomically modern humans found outside Africa are the Skhul and Qafzeh hominins, who lived in the area that is now northern Israel 120,000 years ago. Around 10th millennium BCE, the Natufian culture existed in the area.
Title: Punjab, Pakistan
Content:  The oldest evidence of human life in Pakistan has been found in Soan River valley. It was here that some of the earliest signs of humans have been discovered during the excavations of prehistoric mounds. Tools up to two million years old have been recovered in the Potohar plateau. In the Soan River, many fossil bearing rocks are exposed on the surface. Punjab was part of the Indus Valley Civilization, more than 5000 years old. The main site in Punjab was the city of Harrapa. The Indus Valley Civilization spanned much of what is today Pakistan and eventually evolved into the Indo-Aryan civilization. The arrival of the Indo-Aryans led to the flourishing of 
Title: Yunnan
Content:  The Yuanmou Man, a Homo erectus fossil unearthed by railway engineers in the 1960s, has been determined to be the oldest-known hominid fossil in China. By the Neolithic period, there were human settlements in the area of Lake Dian. These people used stone tools and constructed simple wooden structures.
Title: Greece
Content:  The earliest evidence of the presence of human ancestors in the southern Balkans, dated to 270,000BC, is to be found in the Petralona cave, in the Greek province of Macedonia. The Apidima Cave in Mani, in southern Greece, contains the oldest remains of anatomically modern humans outside of Africa, dated to 210,000 years ago. All three stages of the Stone Age (Paleolithic, Mesolithic, and Neolithic) are represented in Greece, for example in the Franchthi Cave. Neolithic settlements in Greece, dating from the 7th millennium BC, are the oldest in Europe by several centuries, as Greece lies on the route via which farming spread from the Near East to Europe. Following the end of the Greek Neolithic period in 
Title: Shangchen
Content:  The oldest artefact-bearing layer at the site was dated at 2.12 million years ago, while the youngest was dated to 1.26 million years, indicating that the site was occupied (not necessarily continuously) for 850,000 years. Some of the tools were found with bone fragments of animals including deer and bovines. Even older remains may still lie undiscovered, as the deepest layers at Shangchen are inaccessible as of 2018 because the area is "actively farmed". The findings are highly significant as they represent one of the earliest evidence of Homo outside Africa after Masol(fr) in India, surpassing Dmanisi in the Caucasus region of Georgia, which was the previously known oldest Lower Paleolithic site outside Africa, dating to 1.85 million years ago. It is also older than the Yuanmou Man, the oldest hominin fossils found in East Asia, dating to 1.7 million years. As the 
Title: Sumer
Content:  Sumer is the earliest known civilization in the historical region of southern Mesopotamia (south-central Iraq), emerging during the Chalcolithic and early Bronze Ages between the sixth and fifth millennium BC. It is also one of the first civilizations in the world, along with ancient Egypt, the Caral-Supe civilization, the Indus Valley civilization, the Minoan civilization, and ancient China. Living along the valleys of the Tigris and Euphrates, Sumerian farmers grew an abundance of grain and other crops, the surplus from which enabled them to form urban settlements. Proto-writing dates back before 3000 BC. The earliest texts come from the cities of Uruk and Jemdet Nasr, and date to between c. undefined 3500 and c. undefined 3000 BC.
Title: Soan River
Content:  The oldest evidence of life in Pakistan has been found in Soan River valley. It was here that some of the earliest signs of humans have been discovered during the excavations of prehistoric mounds.
Title: Azykh Cave
Content:  The cave was discovered by the "Palaeolithic Archaeological Expedition" of the Azerbaijan National Academy of Sciences under the leadership of Mammadali Huseynov in 1960 and is considered to be the site of one of the most ancient locations of proto-human presence in Eurasia. A Neanderthal-like jaw bone found in 1968 is assumed to be over 300,000 years old and thus one of the oldest proto-human remains found in central Asia. Its discovery gave rise to the term Azykh Man. Archaeologists have suggested that the finds from the lowest layers are of a pre-Acheulean culture (730,000 to 1,800,000 years ago), that resembles the Olduwan culture named after Tanzania's Olduvai Gorge in many respects. The poor quality of the
