Humans have always sought to understand and explain their universe. From the earliest times, myths, superstition, and folklore have been passed down from one generation to another. While we cannot definitively say whether or not, in fact, that disasters occur because the gods are angry, such explanations provide virtually no way of avoiding the problems these phenomena cause. Instead, science attempts to understand the physical causes of earthly calamities and, in doing so, help people to evacuate and avoid places prone to problems. One use of science is to provide solutions to problems.
Science makes no suppositions without investigation.
Neither does it assume there are gods. Scientists know that the more assumptions they put into a hypothesis, the more likely it has a flaw. While some interpret this to mean that science says there are no gods, that is not true. Science simply makes no assumptions about gods. Science survives at least partly because of its useful predictions and objective analyses.
