Consequently, its existence is dependent on something external. This is a basic, intuitive and rational form of reasoning. This is because questioning something that exists that could not have existed is the mark of a rational mind. Think about what scientists do. They point to different features of reality and ask—why is this flower a certain way? Why does that bacteria cause this disease? Why is the universe expanding at the rate that it is? What gives these questions legitimacy is the fact that none of them are necessary; all of them might not have been the way that they are.
