Astrology is one of the greatest phenomena of humanity. Its emergence was not at all controversial, because it was inseparatly operated with astronomy. About 2000 years BC was established that the Moon affects on high tide and ebb tide, so, it was rightly considered that these phenomena can affect man (because our body is mainly composed of a water).
From that moment, the wise men, looking at the night sky above us, thought that, like the Moon, and other planets (and stars) could have a direct impact on man. There astrology and astronomy gradually begin to separate. The first-like pseudoscience, the second-as officially accepted science.
Astrologers (experts in astrology) around the world do not have such a dilemma. The fate of the individual, including humanity, is inseparatly linked with the position of the planets (in astrology, both the Moon and the Sun are seen as planets, no matter what they do not have their physical properties). Therefore, they believe that based on the constant motion of the celestial bodies they can read the future of each of us.
Indeed, it sounds incredible that all born, for exaple, on August 27th, have the same, or similar life path. However, even the astrologers claim that daily, weekly and other horoscopes are useless-worth only personal. And when it comes to personal horoscopes, there are so many combinations that offers billions of options. As much as there are people on Earth.
Personally, I have learned the basics of this ancient skill (or science) and I am not one of those who would believe in all the arguments. The only thing that remains unbelievable is the fact that for four or five thousand years, almost unchanged, there is a learning trusted by millions.
