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. Evidence for this is apparent all around us. We do not turn to the astrology column to get today's weather forecast. We do not read tea leaves to determine if a new airplane is safe before flying it the first time. We do not ask Michael Jordan if a new drug is safe and effective before selling it to millions of people.
