Most likely because we can't even nail down a coherent theory of consciousness amongst humans, despite the fact that we can communicate verbally and use the scientific method. I personally believe that if we assume humans experience some form of high-level consciousness, we must assume that all/most species do too. They have different neural networks, different sensory organs, different communication mechanisms, but they do not LACK these things. An octopus or a bat will experience the world in a vastly different way to ours, not higher or lower. I'd like to see the burden of proof go the other way - what evidence do we have that humans' neurobiology is uniquely suited to consciousness while every other species' is not?
