The way the education system is set up in this society, we learn to be skeptical through our educational experiences with science, math, English, and history. It is not only science that teaches us to be skeptical through the use of the scientific method process. Carl Sagan argues that people should be more skeptical of things that cannot be proven, things for which there is no evidence, and that a way to do this is by learning the art of real science: a science that gives you empirical evidence for human existence and all the things that go with it.
