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 India
Neolithic agricultural cultures sprang up in the Indus Valley region around 5000 BCE, in the lower Gangetic valley around 3000 BCE, represented by the Bhirrana findings (7570–6200 BCE) in Haryana, India, Lahuradewa findings (7000 BCE) in Uttar Pradesh, India, and Mehrgarh findings (7000–5000 BCE) in Balochistan, Pakistan; and later in Southern India, spreading southwards and also northwards into Malwa around 1800 BCE. The first urban civilisation of the region began with the Indus Valley Civilisation.
