Why can constellations represent a person's personality so clearly?

I believe that everything in the world is universally connected. Planets attract and repel each other, interact and influence each other. Man cannot exist in this world as an individual. If you believe that matter determines consciousness, it is not surprising that various constellations affect your character. When you were born, the position and existing angle of each constellation will have a certain influence on you. It is normal that there will be many people in the same constellation.
