While the cited link is broken, the dating of celestial folk tales to remote antiquity is far from a fringe theory. The fact is that some of the earliest recorded information is related to celestial motions (whether for farming or rituals, who knows). Stonehenge is a gigantic calendar, along with MOST other megalithic constructions across ALL cultures. The history book keeps getting pushed further back, sites like Gobekli Tepe depict megalithic construction from around 11000BC (before agriculture) with hieroglyphs and depictions of celestial constellations. The cave paintings of Lescaux depict constellations and religious/magical divination acts. It would be more appropriate to refer to the fields of comparative mythology, theology, and art history as fringe fields :)
