It is a primitive diviner who observes the positions of celestial bodies, the sun, the moon and the stars and makes explanations to predict various things in the world. Astrologers believe that celestial bodies, especially planets and constellations, predict the changes of everything in the world in some causal or accidental way. It tries to explain people's character and destiny by birthplace, birth time and celestial position. All cultures in the world have very different astrological systems and theories. Astrologers also have different views on the scope of application of astrology. Some astrologers think that astrology can objectively predict events that can be verified in the future, while others think that the explanation of astrology is only tendency, it can't predict astrology, it can't make predictions.
