The so-called Indus River is the birthplace of Indian civilization, the Ganges River Basin. Ganges is a major river in South Asia, located in northern India. Before the Aryans invaded India, the Ganges valley had been developed. From some ancient Indian documents or epics, we can understand the importance of this Ganges. Two Indian epics, Rama Yan Na and Mahabharata, have such a magical story. Shiva and his wife Pravaz made love for 100 years, and the ejaculated sperm became Ganges and Seven Rivers. Another way of saying this is that the Ganges fell from the sky when Brahma created the world. This shows the importance of Ganges River to Indian civilization and development.

Born in northern India in the 5th century BC, the Buddha was a liberator who made great contributions to the religious history of India. The theory of reincarnation in ancient Indian thought is the basic background, and then the middle way (four noble truths) is used to relieve the suffering of reincarnation. The Buddha is a very famous practitioner in contemporary ancient India, and the disciples who practice the teachings of the Buddha are called Buddhism, which has been passed down to this day. Buddhism has a great influence on East Asia, Southeast Asia and South Asia.

Sakyamuni means the sage of Sakyamuni. Sakyamuni is the founder of Buddhism. Buddha, the founder of Buddhism, is called Gautama and Siddhartha. The Buddha is called Buddha for short, which means "Awakened". Therefore, Buddha became a name of Siddhartha. According to the records in Buddhist scriptures and traditional views, the Buddha was a white Aryan.

The Buddha has a physical body, so he is actually a historical figure. Just because ancient India did not pay attention to the record of historical years, it is not easy to trace the exact date of birth and death of Sakyamuni. However, according to Buddhist scriptures and inscriptions, there are various legends about the age of the Buddha. According to the research results of modern scholars, it has been confirmed that the Buddha was born in 560 BC and died in 480 BC.

Ashoka was the greatest emperor in ancient India. Ashoka's popularity is unparalleled among Indian emperors, and his influence on history can also rank first among Indian emperors. His achievements in life can be clearly divided into two parts. The first half of his life was the "Black Ashoka" era, which basically unified India through struggle and force, and the second half was the "White Ashoka" era, which promoted Buddhism throughout the country and eventually contributed to the prosperity of this world religion.

The earliest written record of Indian mathematics is the Vedic era, and its mathematical materials are mixed in the classic Vedas of Brahmanism and Hinduism. The age is very uncertain, which is quite different from the age determined by modern people. Its date can be traced back to the earliest 10 century BC and the latest to the 3rd century BC. Veda, Sanskrit Veda, originally meant knowledge and light. Vedas include hymns to gods, witchcraft spells and sacrificial rites. These materials were first recited orally by priests and later recorded on palm leaves or bark. Most of the Vedas of different schools have been lost, and only seven have survived. These Vedas' parts about the design and measurement of temples and altars, sulva sū trus, have some architectural geometric contents and algebraic calculation problems.

In mathematics, the meaning of "0" is varied, which not only represents the concept of "nothing", but also represents the "vacancy" in the numerical notation system. It is the most basic element in the number field, which can be operated together with other numbers and also represents the demarcation point of positive and negative numbers. There is a popular saying that the Indian concept of "0" as "nothing" is related to the "emptiness" of Buddhism (Sanskrit sūnya). There is no clear basis for this statement, but this meaning did appear earlier in Indian civilization.

Mohenjo's archaeological site is located in Lacana County, Sindh Province in southern Pakistan, near the right bank of the Indus River. 1980 UNESCO listed the archaeological site of Yinghao in Mohenjo as a cultural heritage in the World Heritage List.

Today, the earliest civilization in Pakistan developed in the fertile Indus Valley. Around 2500 BC, big cities appeared here, one of which was Mohenjo, a hero in the legal field. At the beginning of the 20th century, an exciting archaeological discovery solved a scientific topic that historians have been arguing for a long time-who was 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.

Mahabharata, a long narrative epic in ancient India, vaguely mentions the destruction of Mohenjo Datum. The poem describes "lightning", "no fireworks", "earth-shattering explosion" and the tragic scene of boiling river and cooking fish at high temperature.

Science has finally temporarily solved the eternal mystery of this history. But is there a new explanation? There is no end to scientific exploration, and what we get is only a temporary period.
