Help me to break astrology belief scientifically

What you are asking us is to prove a negative. That is rarly how science works. For example scientists do not go out to prove that Earth is not rectangular, octagonal, star shaped, etc. Instead scientists start with a hypothesis. In this case that Earth is roughly spherical. Then they use scientific method to prove this theory. The reason for this approah is simple. There are infinite number of negatives to prove with little practical application.

In the case of astrology, the burden of proof is on the people who believe in it. As it turns out their proof normally is subjective and called cherry picking of facts. For example, they read their fortune somewhere and it turned out to come to pass. Well, that is not proof, because for every case of prediction coming true there is a thousand that did not. However, people don't go around documenting all the false predictions. On the other hand the one that came true leaves a deep and lasting impression. It gets told  and retold creating the illusion that all astrological predictions are true...

The Quran is clear on this issue. Allah (swt) says that nobody knows "gheib" or the unknown. This includes the future...

Hope this helps
