Pre-Columbian era
The earliest known civilization is the Olmec. This civilization established the cultural blueprint by which all succeeding indigenous civilizations would follow in Mexico. Pre-Olmec civilization began with the production of pottery in abundance, around 2300 BCE in the Grijalva River delta. Between 1600 and 1500 BCE, the Olmec civilization had begun, with the consolidation of power at their capital, a site today known as San Lorenzo Tenochtitlán near the coast in southeast Veracruz. The Olmec influence extended across Mexico, into Central America, and along the Gulf of Mexico. They transformed many peoples' thinking toward a new way of government, pyramid-temples, writing, astronomy, art, mathematics, economics, and religion. Their achievements paved the way for the Maya civilization and the civilizations in central Mexico.
History of ancient Lebanon
The earliest known settlements in Lebanon date back to earlier than 5000 BC. In Byblos, which is considered to be the oldest continuously inhabited city in the world, archaeologists have discovered remnants of prehistoric huts with crushed limestone floors, primitive weapons, and burial jars which are evidence of the Neolithic and Chalcolithic fishing communities who lived on the shore of the Mediterranean Sea over 8,000 years ago.
