The theory of evolution has critical flaws

Signposting I will open by challenging my opponent's egregious definition of the theory of evolution by pointing out its flaws, presumptions, and straw man-like qualities. Flawed Definition-My opponent defines the theory of evolution as, "the theory that the earth and life began as a result of the Big Bang and that species have gradually evolved over time to form into humans. ". I will show in this round how this definition is not only flawed and presumptuous, but it is also a straw man definition. Presumptuous- My opponent assumes in his definition that the theory of evolution via common descent has anything to do with the beginning of life due to the Big Bang. However, his assumption is false. The Big Bang explains how the universe was born. As Wikipedia states, "At this time, the universe was in an extremely hot and dense state and began expanding rapidly. After the initial expansion, the universe cooled sufficiently to allow energy to be converted into various subatomic particles, including protons, neutrons, and electrons. Though simple atomic nuclei formed within the first three minutes after the Big Bang, thousands of years passed before the first electrically neutral atoms formed. The majority of atoms that were produced by the Big Bang are hydrogen, along with helium and traces of lithium. Giant clouds of these primordial elements later coalesced through gravity to form stars and galaxies, and the heavier elements were synthesized either within stars or during supernovae. " (1) As we can see, the Big Bang Theory only serves to explain how the universe came into existence, NOT how organisms evolved through evolution by natural selection from a common ancestor. Therefore, my opponent's definition is presumptuous. Flawed-Not only is my opponent's definition presumptuous, but it is also flawed, I would argue. If one were to go into Google and search "theory of evolution definition," they would find numerous scientific websites as well as dictionary websites that give generally accurate definitions of what the theory of evolution is. Merriam-Webster;"A theory that the differences between modern plants and animals are because of changes that happened by a natural process over a very long time. " (2)The Free Dictionary; "Change in the genetic composition of a population during successive generations, as a result of natural selection acting on the genetic variation among individuals, and resulting in the development of new species. " (3)Biology About;"Any genetic change in a population that is inherited over several generations. These changes may be small or large, noticeable or not so noticeable. " (4)Oxford Dictionaries;"The process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. " (5)As we can see, I have presented four different sources that fairly define evolution, apart and partially distinct from how my opponent defined it. Possible Straw man-Although I can't say for fully affirm whether or not my opponent's definition is a genuine straw man of evolution, it may be. My opponent's definition brings into question something irrevelant, which, to him makes it seems easier to refute. I can't say for sure, perhaps my opponent is genuinely mistaken or misunderstands evolution. If not, and if he had intent to define it that way to give his position more leverage, then it's not a straw man. But, it is flawed and presumptuous (see above subpoints). Concluding Remarks-I have demonstrated why my opponent's definition of the theory of evolution flawed, presumptuous, and how it may be a straw man. I have provided superior definitions, with sources, unlike Pro and I showed why his definition is sufficient enough if he hopes to argue against evolution. I await Pro's opening arguments in support of the motion that the Theory of Evolution has critical flaws.
