How did you reach that conclusion, truth_b_known?
Animals/insects have a certain level of awareness. Animals insects build structures that have function, but do not having meaning or purpose. That is to say, wildlife have been witnessed to make structures to reside in. Whereas human build structures to reside in (function), but also build structures that have purpose. Examples are structures used for religious practice (church, temple, etc.) or for education (school, university, etc.), or to maintain order (capitol, courthouse, etc.)
Wildlife sees the structures human make. Wildlife is not aware of the purpose of the above describe structures. Wildlife can only see the functionality (a place to seek protection from elements/threats) of the structures. This is due to a lower level of consciousness/awareness.
What I theorize is that there may be life with a higher level of consciousness than our own. As such, we may not be able to comprehend it as our own consciousness is not high enough. The problem then is how does one prove this without raising one's awareness or level of consciousness? The answer may be - you don't.
