Answer:
Hinduism:
Most scholars believe Hinduism started somewhere between 2300 B.C. and 1500 B.C. in the Indus Valley, near modern-day Pakistan. But many Hindus argue that their faith is timeless and has always existed. Unlike other religions, Hinduism has no one founder but is instead a fusion of various beliefs. Unlike other religions, Hinduism has no one founder but is instead a fusion of various beliefs. Around 1500 B.C., the Indo-Aryan people migrated to the Indus Valley, and their language and culture blended with that of the indigenous people living in the region. Hindus have many deities. Hindus believe in the doctrines of samsara (the continuous cycle of life, death, and reincarnation) and karma (the universal law of cause and effect). One of the key thoughts of Hinduism is “atman,” or the belief in the soul. This philosophy holds that living creatures have a soul, and they're all part of the supreme soul. Hinduism reinforced a strict social hierarchy called a caste system that made it nearly impossible for people to move outside of their social station. Emperors during the Gupta empire used Hinduism as a unifying religion and focused on Hinduism as a means for personal salvation, so yes it does support the caste system. Sacrifice plays an important role in Hinduism, although the rituals associated with it have evolved over Hinduism's several thousand years of existence. The Vedic scriptures dictate the rules of sacrifice and priests follow highly structured methods of incorporating sacrifice into worship.
Buddhism:
Buddhism is a faith that was founded by Siddhartha Gautama (“the Buddha”) more than 2,500 years ago in India. With about 470 million followers, scholars consider Buddhism one of the major world religions. Most Buddhists do not believe in God. Although they respect and look up to the Buddha, they do not believe he was a god but they worship him as a form of respect. Buddhism emphasizes the notion of ethical sacrifices, acts of self-discipline, and there are instances of devotional offerings, such as burnt incense, to the Buddha. The basic doctrines of early Buddhism, which remain common to all Buddhism, include the four noble truths: existence is suffering (dukkha); suffering has a cause, namely craving and attachment (Trishna); there is a cessation of suffering, which is nirvana. Buddhists do not support the caste system, but to some extent are drawn into it with their two-tier system and social pressure
