Astrology Pandit Anyone?

With the latest new sunsign fiasco going on, I begin to wonder do people really really believe in astrology or is it simply fun for lack of a better brain stimulating activity?? How can we: the 21st century modernized cultured people even think about the possibilities that a heavenly body made from chemicals,gas and light have an effect on earthlings who reside millions of light years away. The entire idea is ridiculous and a bit amusing as well!
