The thousand-year history of Azerbaijan let us know that here at different times people worshiped different religions. Among them were religions like paganism, Judaism, Christianity as well as Zoroastrianism. Zoroastrianism is a religion based on fire worship. Fire worship originated in the first millennium BC, and according to some sources, Zoroaster, who was the main prophet of fire worship, came from Azerbaijan. Also, as in many mature religions, Zoroastrianism has the concept of good and evil, and good always overcomes evil. The god of right deeds, goodness and justice was called Ahura Mazda. And the god of anger, evil and bad deeds was called Ahriman. Naturally, there were many more followers of Ahura Mazda than the god of evil, so good always defeats evil and the followers of good and faithful deeds will find eternal life and happiness in the next world.
27 kilometers from the central streets of Baku in the settlement of Mehemmedi there is a limestone mountain on the slope of which a hot gaseous medium flares up. This eternal flame includes Yanardag, which means fiery mountain. Scientists have determined that the eternal fire is about 5000 years old and it was he who served as a source of inspiration for fire worshipers in Azerbaijan. The fiery mountain was formed during a thunderstorm when lightning struck the trees near the mountainside and the flames flared up due to a leak of fuel supply gas. Azerbaijan has a large number of sources of gas in the form of a flame. Not for nothing is Azerbaijan called the “land of fires”
