"Egyptian astronomy began in prehistoric times, in the Predynastic Period. In the
5th millennium BCE, the stone circles at Nabta Playa may have made use of astronomical alignments. By the time the historical Dynastic Period began in the
3rd millennium BCE, the 365 day period of the Egyptian calendar was already in use, and the
observation of stars was important in determining the annual flooding of the Nile." -

"Astronomy in China has a long history stretching from the Shang dynasty, being refined over a period of more than 3,000 years. The ancient
Chinese people have identified stars from 1300 BCE, as Chinese star names later categorized in the twenty-eight mansions have been found on oracle bones unearthed at Anyang, dating back to the mid-Shang dynasty. The core of the "mansion" (宿
xiù) system also took shape around this period, by the time of King Wu Ding (1250–1192 BCE)"

could contain the oldest known star chart (resembling the constellation Orion)."

I highlighted in red where uncertainty is left. While most of your accusation of our ancestors' lack of knowledge/understanding is accurate, it contains inaccuracies as well.
Personally, I wouldn't presume how little or how much someone understands something without substantial evidence, of which most has not and could not have survived this long. It's come to our understanding that the Neanderthal had larger brains than ours and were likely more intelligent and socially adept. I'm just saying that
our understanding of
their understanding, has changed... and this underestimation of other or overestimation of self isn't an uncommon error.
For centuries (if not still today) we taught students using
orreries or images such as the following:

Does this mean we actually believe the solar system look like the simplified models?
We teach/taught students that molecules and atoms are:

We don't lack understanding of these structures even though these models are inaccurate to the actual reality. However, our descendants could very well come to such a conclusion, if there were limited surviving archeological evidence to our civilization after we destroy it.
I'm not so certain our ancestors lacked understanding of much of the natural world they inhabited. I think credit is deserved where credit is due, and all of our modern sciences are birthed from religious literature and world views. Without those idiots, we couldn't be the idiots we are today.
