>Primates use rocks/sticks as tools. >Dolphin's have a language that is intelligent. >Morality is found in a variety of animal species. >The existence of a higher deity is unproven. >The human mind's natural tendency to be religious is now known to have been an evolved trait that helped bring together early tribes of prehistoric humans, not unlike how wolves instinctually form packs. Human tribes with a common mythology and belief system were more likely to stick together and survive than others, and religious humans soon became the norm. Additionally, many modern-day people who suffer from temporal lobe epilepsy tend to become extremely religious and occasionally claim to have a special link to God, similar to prophets from the early days of religion. The obvious conclusion is that the religions that we know are constructs of the human mind that are linked to our biology. Religion is just another adaptation, and could very well be found in other animals. So no, we're not special from a biological standpoint. However, we are overall the most successful species on our planet, and are unique in that we have the luxury to ponder our own existence.
