Final answer:
Ancestor worship is the practice not associated with Indian civilizations among the given choices. Sanskrit, Hinduism, and Buddhism have roots in India, while ancestor worship does not traditionally belong to these Indian religious traditions. Key history points about Indian religion include the Aryans bringing the Vedas, the origin of the caste system, the Delhi Sultanate introducing Islam, and the evolution of Hindu deity worship.
Step-by-step explanation:
The entity not associated with Indian civilizations from the given options is ancestor worship. While Sanskrit is an ancient language used in India, Hinduism and Buddhism are religions that originated in India, ancestor worship is not a practice that is traditionally part of these Indian religious systems.
The name of the hymns the Aryans brought to India is the Vedas. The Aryans are also the group of people who originated the Hindu caste system. In the caste system, the group that occupied the highest tier is Brahmans (priests). Additionally, the rulers of the Delhi Sultanate were followers of Islam. Among the nomadic cultures that lived on the Inner Asian Steppe, the Yangshao is not one of them; they were an ancient Chinese culture. When discussing the socialization of people by religion, it is not correct that an individual's personal internal experience of a divine being leads to their faith; rather, faith is a complex interaction between personal experience and collective traditions or teachings.
In the historical context of India's religious evolution, the Delhi Sultanate's rulers introduced Islam to northern India, whereas the south retained predominantly Hindu beliefs and practices. Hinduism evolved to include personal devotion and the worship of gods such as Vishnu and Shiva, along with their consorts and female deities. In contrast, Hinduism's founder cannot be definitively stated since it is based on a collective of ancient practices and texts, but certainly, neither Krishna nor Buddha founded Hinduism; rather, they are associated with different aspects of its history and development.
