Hi Pepper,

Hinduism, the world is oldest religion - it goes back at least 5,000 years. No one know exactly when it began--it started before people recorded history. It has no human founder. Hinduism has four main denominations--Saivism, Shaktism, Vaishnavism and Smartism.

Thanks for the great question,
