The origins of Hinduism are unknown. This is primarily because Hinduism is not a single system of beliefs but a collection of various beliefs and practices that have evolved over time. Most Hindus believe that their religion is eternal and has always existed. Historically, Hinduism is said to have been present since at least 6500 B.C. Previous theories credited the Aryans with the rise of Hinduism. Scholars, however, have had difficulty providing physical evidence to substantiate that theory. The first Hindu writings appeared around 1500 B.C. Prior to that time, Hinduism traditions were mainly oral and involved stories starring hundreds of gods. Source: https://www.reference.com
