There is a New Age belief: “There is no evil and the proof is looking at nature. There’s no evil in nature, therefore it must not exist. What we call evil is just an expression of human free will and negativity.” What is Creator’s perspective?

Unfortunately, this is a quite misguided and naive perspective that proceeds from assumptions to shape the narrative and concludes with a cursory look at nature that ignores abundant evidence to the contrary. First of all, human beings are a part of nature, and a big part, yet there is much evil in human doings. So to assume that nature, simply by setting the reality of existence of humans aside, makes a convincing argument that "Evil is not real" is a sleight of hand verbally but not an argument that holds up to reason and logic. Even apart from what humans contribute in the way of negativity to nature, there are abundant examples of evil in the workings of nature. First of all, there are many, many predators whose mode of existence is heartless and cruel to their prey, sometimes humans included. If you ask people who have been attacked by wild animals, they will give you an earful about how their lives have been changed and scarred by an encounter while swimming with a shark, or while walking in the woods and a large beast with claws and fangs that savaged them. If you look at the plight of the many animals subjected to quite cruel death at the hands of predators uniquely designed to outmatch them, it is hard to not be upset and even repulsed by the tragic events that are commonplace on a daily basis. This is not to mention the many scourges where there might not be a life-threatening influence, but certainly a large reduction in quality of life for many creatures who cannot seek shelter like humans and are subjected to an onslaught of mosquitoes and ticks and parasites of all kinds, not to mention the microbial scourges bringing epidemics, chronic illness, and a weakening they cause to shorten lifespan. One can make quite a list of individual behaviors that are unnecessarily harsh and cruel as exhibited by the shrike which seems to kill for pleasure and not for food. There are many examples of predatory species tormenting their prey, so we would say that if you look deeper, you will find evil in abundance all through nature, humans included, but it is the footprints of interlopers, both dark spirits and extraterrestrials. They have contaminated your world with those very predatory species as well as the microbial scourges assumed to be a natural product of evolution but, in actuality, are extraterrestrial bioweapons imported here via spacecraft. This is not to mention the exaggerations of natural forces of weather like droughts and floods, blizzards, lightning storms, tornadoes, and hurricanes, some of which are entirely unnatural and others subject to being worsened through extraterrestrial technologies, specifically to rain down evil on human beings by tormenting and causing suffering. So this belief that "Evil does not exist because it is absent from nature" is a better illustration of how humans are so easily programmed by extraterrestrial mind control manipulation to adopt a simplistic idea as valid and all one needs to know, when the opposite is the case.
