How Did Hinduism Spread?
When inhabitants of the Indus Valley fled their home, they spread Hinduism across the land when they resettled in India. To this date, archaeologists are not sure why the inhabitants left the Indus Valley in such a hurry.
When the previous inhabitants of the Indus Valley moved to India, they encountered people from central Asia. These people brought their own religion and customs, including their religion, Vedism. Archaeologists believe that this religion combined with that of the Indus Valley to create what is now known as Hinduism. Hinduism is marked with statues of the religion's gods and goddesses, as well as temple tanks that were used for bathing.
