Objective Morality Does Not Exist, Regardless of the Biblical God's Existence

Excellent. Thank you for accepting this debate challenge.Moral BiologyI shall open by stating that many organisms have evolved as social organisms. Through the process of evolution (via natural selection and mate selection), these organisms (as a population) developed the sense of empathy that we are all so innately familiar with [1]. Modern neuroscience explains that this phenomenon is a process or function of the brain [2]. Empathy is simply the ability to vicariously experience and understand the emotions of another being, and emotions themselves are a result of the processes of the brain [3].However, empathy and morality are not a universal constant. For example, consider the Black Widow Spider's tendency to devour its mate[4], which is an evolutionary trait [5]. To our standards, cannibalism is almost unanimously viewed as highly immoral and repulsive and as such, we regard this as a horrifyingly immoral act. If the spider shared this same view (well, I'm sure the male does), it would not be so frequently performing this act. The spider is driven by biological and psychological factors, and clearly doesn't see this action as "wrong" or "bad". This demonstrates that he judgment of morality lies in the beholder.It is quite easy for us to acknowledge that there are actions that are universally right and wrong, but that is because we are all the same species (human) and as such, have very similarly developed brains, which is the very source of this judgment. To continue this point, empathy isn't universally the same within even our own species. If the act of killing is universally "bad", why can we so easily kill a fly or mosquito but shudder at the thought of killing a puppy? The basis of this judgment is a result of the feeling that we get as a result of our evolved, socially-based cognitive development.The above indicates that the source of our morality lies within ourselves. Specifically, within our psychology and emotions and as such, is subjective.Moral ValueLike other comparative descriptive words, morality depends on a value which is then compared to other possibilities. A similar descriptive word would be "large". If something is assigned the label of "large", it is based completely on its size relative to other objects. Compared to a pebble, a boulder may be large but then, if compared to a planet, it is not. A single object in existence cannot be described as either large or small because there is nothing to compare it to. This is, of course, unless one believes in objective largeness.Morality is similar to this because it can clearly be recognized as some actions hold a greater degree of wrongness than others. An observe attaches a value to the subject (based on empathy and emotion) which represents a moral judgment, and that judgment is only applicable to that particular observer. Certainly, different observers can associate the same general value with a given subject, but each individual's perspective is their own.[1] http://greatergood.berkeley.edu...[2] https://www.psychologytoday.com...[3] http://www.humanillnesses.com...[4] http://www.livescience.com...[5] http://www.livescience.com...
