while this hints at deep astrological knowledge it is not above human knowledge alone.

I have tried to find it, there is an artifact which has been depicted to show lunar seasons, and it has been observed that is may state a time when conception in females is best, due to available resources for child-birthing and child-rearing. I believe it is around 45,000 years old, not sure if it is wood, bone or ivory. A women giving birth at the end of winter beginning of spring has a much better chance of raising that child successfully compared to a woman giving birth in late summer, the fall or at the start of actual winter. This being the case humans may have times their conception after studying the stars and may had had elaborate sexuality rites unaware as to how conception actually occurred.

The device you posted an image of, while considered advanced for the Greeks at the time is no 45,000 years old..... but does explain how humans may have had a deep ancestors connection to the movement of the moon, stars, and planets.

If anyone knows what I am referring to it was found in North western Europe
