A useful book in English proves the weakness of man in comparison with other creatures, and even the microorganisms that may decide his fate, Allah willing. They may eliminate human beings through deadly diseases. As a result, we have to search for their secrets and the great creator who created them. These creatures prove that whatever we think we become knowledgeable of the world in which we live to the extent that we can control it, we may stand helpless in front of a tiny creature. As a result, religion is so important as science.
