Evolution (if you’re a creationist then there’s no point in joining this discussion, you already have the answer) has produced humans with great intelligence and consciousness. Why isn’t there some species that is pretty intelligent, just not quite as much as us?
Why don’t we see primates making crude hammers or building shelter? Beavers build shelter but the argument is that is instinctual rather than intelligent. Dolphins are said to be pretty intelligent but it’s hard to compare to humans because they haven’t developed any technology. Some animals have sophisticated means of communication (elephants through ground-stomping, whales, bees) but none of this is said to be language.
So how did humans get so far out in front, when the rest of the animal kingdom has a smoother spectrum?
