Find me, in the animal kingdom, a single species that claims to build nests. Not any that do it that we can see, just those that claim it. What about scaly marine vertebrates who appear to be fishes but do not claim it?
Human beings are animals whether or not we were created 6,000 years ago or evolved through a complicated process beginning 3.75 bya. Our species is subject to the same physiological constraints of any other given our environments. History has no bearing. Our opinions of ourselves has no bearing.
Because of our particular trait of language we have a unique opportunity to examine the minds of our fellow humans. But we do not know what happens in the minds of other animals, or even if they have minds as we understand them.
