Religious cosmology, or religious cosmology, is a general concept used for conceptions of the universe based on religious thought and judgment, not scientific evidence. Although the religious cosmology of each religion diverges due to the fundamental differences of the religions, similar points can also be found. The reasons for similarities can be various, as well as related to the basic features of religion. For example, in the majority of monotheistic religions there is the conception of a single god that created the universe, and this god is often believed to have created the universe from nothing. In religions or sects that do not have basic divine features, the creation of the universe can be described as a spontaneous event as a transition from chaos to order rather than an act of creation. Religious cosmology is also important for the science of religion, as it reflects and emphasizes the priorities and fundamental concepts of a religion. In ancient history, religious cosmology was integrated with scientific (or physical) cosmology in the sense we understand today, either because there was no particular discipline that was accepted and distinct from religion, or because religion was the main authority in many aspects of life.
