Science is a knowledge system that reflects objective laws. Scientific knowledge sprouted from early human social practice, and ancient civilization already contained many factors of modern scientific development. Due to the historical limitations of human social practice and understanding, ancient scientific knowledge has been attached to the natural philosophy system of thinking mode for a long historical period, and even parasitic in religious myths. In the Middle Ages, science became a branch of theology. The historical mixed state of science and religion gradually disintegrated with the development of human social practice and understanding, and science was separated from natural philosophy system and religious myth and became an empirical science. 1543, the publication of Copernicus's Theory of the Operation of Celestial Bodies declared the complete break of modern scientific and religious world outlook for the first time. Since then, natural science has been liberated from religious theology, the development of science has made great strides, and science and religion have embarked on the road of open conflict.

Science and religion are essentially opposites. Science does not recognize any supernatural power, and opposes using supernatural reasons and forces to prove any natural phenomenon and its development process. Religion, in essence, worships supernatural forces and believes that supernatural gods dominate the world. The essence of religion determines the inevitability and law of its denial of objective existence. The affirmation and negation of supernatural power determines that the essential opposition between religion and science is irreconcilable. Religion and science also have essential differences in cognitive styles. Natural science starts from all kinds of real forms and motion forms of matter, understands all kinds of connections of things, and proves them with experience as much as possible. The basic way for religion to know its belief object is belief, relying on transcendental, irrational revelation or mysterious intuition. In terms of social functions, religion and science are also very different. The development of science and technology has created enormous social productive forces, thus promoting social development. Marxism holds that science is the revolutionary force with the highest significance. Although religion has played a special role in promoting social development through religious movements under specific historical conditions, in general, religion is a conservative factor in historical development. Because religion often regards the existing social system as the embodiment of God's will and as something sacred and inviolable.

In history, any major achievements made by science in every field mean the discovery of natural laws and the denial of supernatural forces in this field, which means the elimination of mysterious functions and ignorant influences in this field. Since17th century, the process of eliminating God's domination from all fields of nature, which started from modern experimental science, is unstoppable. From17th century to19th century, the evolutionism represented by Descartes, Kant, Laplace and Darwin has made great achievements in astrophysics, geology, biology and other fields, and formed the celestial evolutionism, geological development view and biological evolutionism which are directly opposite to God's creation belief. /kloc-since the 0/9th century, the great development of natural science has made the expression of natural laws more perfect. For example, modern physics has found their respective applicable conditions and scopes for classical mechanics, relativity and quantum mechanics, and organically unified the relativity of high-speed motion, classical mechanics of conventional motion and quantum mechanics of micro-world, further proving the speculative components of theological world outlook. The new discovery of natural laws and the new progress of natural science always inevitably lead to a further understanding of religious theology.
