There are only about 3,000 Kalash polytheists and 3000 Kalash Muslims. The Kalash people live in three isolated valleys. They claim to have a Greek origin. The Kalash have a polytheist religion, while neighboring peoples are Muslims. If a Kalash person converts to Islam, that person is kicked out from Kalash society. This is the reason why the Kalash religion still exists and this is the only way to make it exist also in the future. The Kalash are also known for their human features. It can vary from someone with light brown skin, brown eyes, and black hair to someone with white skin, blue eyes, and blonde hair.
