The Greeks and Babylonians measured the position of planets relative to the background stars. In their system, the Sun moves east, not west. For example, the Greek Antikythera mechangism had planetary gears and even variable gearing to move the Sun, Moon and planets east through the ecliptic stars. Evidently they could use it to predict eclipses.
However it was not necessary to imagine conjunctions happened in time. In fact, even the Greeks could not imagine that time was linear. Such an idea violated the observations that the Sun, Moon and planets change speed, relative to the background stars. (Even the Greeks used the Babylonian System B to approximate how the Sun changes its angualr speed (angle per day) relative to the stars.
Ptolemy compared Babylonians eclipses from 800 years before with ones he observed. He used the Egyptian astronomical calendar that had a fixed number of days in a year. (This was great for counting days between events, but a winter month would eventually become a summer month). By dividing the number of days by the number of lunations, he could find the average days in a lunation, down to tiny fractions of a day.
However, this was not a measurement of time, in the Babylonians system. It was just the average number of days in a lunation. Yet each lunation was observed to vary, as they still do today.
When we add our philosophical notions of time to the Bible, we alter the creation account. Moses lists the days of creation as changes, mornings and evenings, not time. He counts the days, not philosophical notions of time.
Yet we confirm his words with the only history that we see exactly as it happened, long ago. Billions of naked cores of primordial matter spread out, sending out tiny globs packed with stars. The star streams spread out, often growing into local growth spirals. The atoms, the orbits and matter’s volume keep shifting throughout the visible cosmic history. What we see confirms the text, that he commanded them to become spreading things (raqiya). The bible repeatedly uses eon words for the age of the Earth. Yet it also counts few years. Jacob said the days and years of the son are shorter and worse that the days and years of the fathers (Genesis 47:9). There is a simple reason why. The pull of the Sun has an aberration. It gets delayed by the light distance. Thus, it pulls more on the dawn than the sunset. Gravity’s aberration , steadily accelerate rotations and orbits (days and years) as it pushes all orbits outward. Meanwhile the sun changes from red to white. The orbits of solar planets, exoplanets and the arms of billions of spirals galaxies have logarithmically increasing distances to their origins.
Change and science are diametrically opposite worldviews. Only the changing worldview supports the visible creation of the galaxies.
