I actually think it is a very insightful point, just not for proving either sides of this argument, for this purpose it is useless.

In the case of astrology, I find interesting how a few millennia of human culture, stories, and epics have been projected on celestial bodies and carried along our history through this shared medium.

I would say that (if you really want to find a strong point) astrology can be seen as trying to distill human knowledge from our cultural substrata.

Whether we should do it or not is another topic.
