True science asks us to be cautious. Just as we should be careful with the priests, so we should be with the scientists. Begin with disbelief. Analyse, test, prove everything, and then take it. Some of the most current beliefs of modern science have not been proved. Even in such a science as mathematics, the vast majority of its theories are only working hypotheses. With the advent of greater knowledge they will be thrown away.
