Cosmology is amongst both the oldest and youngest of sciences. In its primitive form, it can be traced back to prehistoric eras, for instance through the well-established astronomical alignments of pyramids and stone circles. As well as religious motivations, study of the skies was essential to develop timekeeping so that, for instance, crops could be planted at the correct point of the seasonal cycle.
