When you think of "Astrology" you probably automatically think of people asking "What's your sign" and talking about how their future will go based on a website. That is not what Astrology is, that is just how it sells. Astrology is how we farm, it is how Calendars were made, and much much more.
Calendars seem like a normal part of life now, but there was a time when Calendars did not exist. In ancient Egypt they would make fake Horizons and make a mark where the sun came up every day. And by doing this, they made pretty much a perfect year, because the Sun moves across the Horizon throughout the year. And you have probably never thought about it, but a "Month" is actually based on the moon, you could call it a "Moonth". Each month gives us about 1 full moon. Also, Sunday is "Sun Day", Monday is "Moon Day", etc.
A lot of people think that the Horoscopes are just random star system that people decided "That one looks like a goat" and "That one looks like a lion" and "That one looks like a guy carrying water", then they randomly assigned months to stars. But that is not what happened. Those specific constellations are the specific constellations that the Sun seems to pass though as we go around it.

Before Gravity was discovered they thought the Planets controlled the Ocean. And the reason Jupiter/Zeus has a lightning bolt is because they thought the planet Jupiter controlled lightning. Even the Hebrew people knew about Mars. The Egyptians called Mars "Horus of the Horizon", the Hebrews called it Ma'adim (מאדים) — "the one who blushes". The symbol for Mars is the symbol for "Male" and the symbol for Venus is the symbol for "Female".

Astrology is actually a distorted misused form of Ancient Religions. Most of the time Ancient people didn't look to Horoscopes for things like dating or changing jobs, but instead they looked to it for things like farming. Where the could "predict" when to plant their crops, and "predict" when they were going to be able to harvest. We still do this today in the form of "The Old Farmer's Almanac" the Almanac can predict the weather and the planetary alignments and everything.

Hindus OPENLY Worship Gods that Correspond with the Planets. If you look up "Hindu Equivalent to Mars" you will find it. If you look up "Hindu Equivalent to Luna" you will find it. The Greeks and Romans had a similar faith, which the Egyptians and Sumerians had first.
