One story stands out to me in particular. Erlik, a deity in Mongol mythology, was either the brother of or created as the first human by the supreme god Ülgen. I read that Erlik wanted to become equal to Ülgen and supposedly tried to seduce humans to take the forbidden fruit from the first tree, and as a result, Erlik was banished to rule over the lower world and assume a position akin to the Christian devil. Was this myth around before Christian influence? In what ways did Mongol mythology change after coming into contact with Christianity?
