Hinduism is an Indian religion or dharma, a religious and universal order by which its followers abide. The word Hindu is an exonym, and while Hinduism has been called the oldest religion in the world, it has also been described as sanātana dharma, a modern usage, based on the belief that its origins lie beyond human history, as revealed in the Hindu texts. Another endonym for Hinduism is Vaidika dharma.

Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers. They migrated out of Africa during the Last Glacial Period and had populated most of the Earth by the time the Ice Age ended 12,000 years ago.
