Indian civilization is one of the oldest civilizations in world history. India, China, Egypt and Babylon are also called the four ancient civilizations. The ancient Indians invented ten numerical symbols, including zero and decimal positioning and counting methods. India is located in the South Asian subcontinent, and its name comes from Sanskrit Sindhu, ancient Persian Hinduism and the Indus River in ancient Greece, which originally referred to the Indus River. Indian civilization originated in the Indus Valley, which was called Indus Civilization in history. Historians have long debated a scientific topic-who is the master of ancient Indian civilization. With the discovery and excavation of the ancient cities of Harappa and Mohenjodaro, the fog was finally cleared away, and history announced to the world with its irrefutable truth that it was the Dalovitas who created the splendid civilization of ancient India, not the invading Aryans. The Indus Valley is undoubtedly one of the cradles of world civilization. Later, the center of Indian civilization gradually moved to the Ganges River basin, and Buddhism rose one after another. Buddhism is one of the three major religions in the world. At present, there are more than 65,438+0,000 followers in India. According to legend, it was founded by Sakyamuni in northern India in the 6th century BC and named after the Buddha. As a heretical religion against Brahmanism, primitive Buddhism advocates caste equality and pursues personal liberation (nirvana). Buddhism was widely spread by Ashoka in the 3rd century BC. It is said that Asoka once built 84,000 pagodas, and the oldest existing three-foot pagoda was built in the time of Asoka.
