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.
Byblos
The site first appears to have been settled during the Pre-Pottery Neolithic B period, approximately 8800 to 7000 BC. Neolithic remains of some buildings can be observed at the site. According to the writer Philo of Byblos (quoting Sanchuniathon, and quoted in Eusebius), Byblos had the reputation of being the oldest city in the world, founded by Cronus. During the 3rd millennium BC, the first signs of a town can be observed, with the remains of well-built houses of uniform size. This was the period when the Canaanite civilization began to develop.
