So it seems obvious that astrology is just hocus-pocus , the remnants of our ancestors from a time before modern scientific and technological advances, a mere vestige of our ancient past that continues to live on in modern times in the deluded minds of people even today. Although it may seem obvious , as explained above, that astrology is a superstition, anyone who studies astrology seriously will be shocked to discover that there is validity to astrology. There are many theories but no proofs. The fact is that we do not know how astrology works. If you don't know how astrology works, then doesn't that prove that astrology is not scientific.
Science is based on observation.
More specifically, science is based on the scientific method. Theories are extremely important in science because theories help the scientist make predictions of how things will behave in a new context. Without theories, science would proceed at an incredibly slow pace. But one can make clear, indisputable observations without any theory at all. For example, I can predict that any heavy object dropped from a table will fall to the ground.
