The book of Enoch talks a lot about the "Watchers", angels who God appointed to watch over the earth. Later Jewish myths and legends also deal with the Watchers, the fallen angels, and such. Is it possible that the Jews got these ideas from Babylon? Selah:
They are considered an old race who have gone past the need for physical bodies. Some claim they are light. There are legends that say they came from the stars. They are the ones known as the Watchers. It is claimed that each of the four Watchers reigns over one of the four directions of the circle.
There were star cults in Mesopotamia around 3000 bce. One of the beliefs of these cults was that there were four major stars, each ruling over one of the four cardinal points. These stars where known as "Lords" or "Watchers."
The Watcher of the East was the star Aldebaran.This star marked the time of the Vernal Equinox. The Watcher of the South was Regulus, marking the time of the Summer Solstice. Marking the Autumnal Equinox was Antares, Watcher of the West. The North Watcher was the marker of Winter Solstice, Foralhaut.
Actual towers, called Ziggurats (cosmic mountains) were built as a form of worship. Each tower bore the symbols of the Watchers. During ritual celebrations the symbols were traced in the air with torch flames or wands, and the Watchers names were called.
The Watchers were thought of as gods that guarded the heavens and earth. Lunar and Solar cults eventually replaced the Star cults.
The Watchers became the gods of the four winds to the Greeks. The Christians took them over as "guardian angels."
The Hebrews taught that all angels, known to them as Watchers, were ruled by four "higher" angels. They became the "Archangels" to the Cabalists.

Just because the Babylonians believed something doesn't mean it is false. Some of the earliest records we have of the Lunar Sabbath are found in Babylon. The Babylonian account of creation, the flood, and fall of man is exactly the opposite of the Bible account, like a mirror image, detail for detail. Caution is needed. I hope the information quoted above is edifying; I can't vouch for its accuracy.
Precession of the Equinoxes:
Precession causes the cycle of seasons (tropical year) to be about 20.4 minutes less than the period for the earth to return to the same position with respect to the stars as one year previously (sidereal year). This results in a slow change (one day per 71 calendar years) in the position of the sun with respect to the stars at an equinox. It is significant for calendars and their leap year rules.
