Celestial bodies have long been a source of religious objectification and this article aims to convey the origin of the relationship between human religious belief and observations of the night sky. The academic search for the origin of religion commenced in the early nineteenth century and since then the debate of whether animism or pre-animism is the original religion has dominated this field. Until now, no unified theory has acknowledged the influence of primitive astronomy on the origin of religion. However, (...) the theory of Astronicism supports the pre-animist hypothesis by proposing that early modern humans of the Upper Palaeolithic made simple associations between celestial bodies and their apparent capacity to determine human survival. This article asserts that these associations led to celestial deification long before humans animated astronomical phenomena with spirits. Archaeological specimens from Europe and beyond including astral rock art, cup marks and engravings are used in this article to assert that astrolatry and astromancy were crucial to the development of religion.
