Explanation: Contrary to the theory of creationism, according to which everything is created in the beginning as it is created and the characteristics of animals, plants and humans are the same from the beginning, Darwin's theory of evolution speaks of the gradual development of the qualities necessary for survival. Thus, according to the theory of creationism, the Earth is not very old, at least not as much as was necessary to justify Darwin's evolution. The changes described by Darwin take millions of years, so the theory that the Earth is very old is quite in favour.
