He came to this conclusion by investigating how “the geocentric theory did not accurately explain the movements of the sun, moon, and planets” (Doc. 2) This article was written from a 3rd person point of view, with the intended purpose of educating the public on why Copernicus came up with the heliocentric theory. This piece of evidence shows one example of where logic and reason was more accurate that the beliefs of the church about the geocentric theory.
