I'll pose my own naive theory: Consciousness is a type of thought. When we zone out, we stop being conscious to an extent. Bugs don't experience those thoughts about themselves so they're not conscious (just a wild guess). Consciousness ceases when we are focused solving problems. It returns the moment we think about ourselves. So, what is a thought? Why are there some types of thoughts that only humans can have? I do not know.
