I believe it's too far fetched. 

Only two celestial objects effect life on Earth, The Moon and the Sun,

From Astronomy, the other planets themselves are so far away that they have zero effect for life on Earth. let alone stars billions of light years away, 

Before a strong understanding of science, humans used starsigns to predict the climate, sacrifice etc.

Imagine never being told what a star is physically. Look to the night sky and what? Gods? A soul? Ancients just took it face value.

Does astrology still divinate on the moon, or mars? 

Its white girls replacement for religion.

i believe astronomy works because society runs on cycles, which can be mapped to the stars. I'm also happy to believe it's magic stars, though. You don't have to prove why astrology works before you know it works, there's always something you don't know
