I repeat, adapting to your rhetoric: It is impossible to "uncover the unknown and make it understandable" if fantastic creatures can emerge from their invisible, illogical supernatural universe on a whim at any moment and, by using powers that are not constrained by the laws of the natural universe, can make literally anything happen. Such as tripling the amount of water on the earth and then draining it off. No, it discovers laws and principles. The most basic is that the natural universe is a closed system. Gods are imaginary. This is not a claim, assertion, or assumption. It is a theory derived from hundreds of years of empirical observation. Like all scientific theories it is accepted as true beyond a reasonable doubt, meaning that the Rule of Laplace will be automatically invoked if someone claims that he can falsify it. This theory is tested everytime someone performs an experiment and observes that no gods, angels, demons or other supernatural forces appear in the laboratory to perturb the outcome. No scientific theory has been tested as thoroughly as this one. It is the foundation of the canon of science.
