At first glance, distinguishing the main difference between humans and animals seems too simple: Humans have the intelligence and capability to perform complex tasks (such as religion), and animals do not. Upon deeper inspection, however, I’m not sure that answer satisfies. While it may be a correct and concise answer, it may not be the complete answer. For example, some species of dolphins or chimps are very able to perform difficult tasks. While highly intelligent in the animal world, they lack a necessary component of human intelligence, introspection. It is introspection and a craving to fill any empty feelings that lead humans to religion. Without that introspection and need to fill intangible voids, animals are happy to just exist. If humans could be satisfied with food, water, shelter, and loving attention, there would be no need to seek higher answers. So maybe the main difference between humans and animals is merely that people have more needs to be satisfied than animals.
