I find your comment ironic. Consider that you are stating that everything must, at some level, be like humans. This is the most clear cut example of anthrocentric thinking I can imagine! This view is also contradicted by experiment which shows that creatures that are extremely genetically similar to us, still respond very differently to various stimuli thus making the logical view that they indeed do experience the same stimuli in different ways.

Beyond experiment I think it also fails through basic logic as well. Evolution dictates what we become, and we can see the vast variety of changes that evolution has forked among us. Go back far enough and even humans and plants share a common ancestor. To this day a banana shares about 60% of its DNA with a human! But of course it's not just what's on the outside the evolution changes. The way things act, behave, perceive, think, and so on is also controlled by evolution. To assume that somehow everything must, at some level, have internal mechanisms similar to a human is also just not very logical. It'd be like suggesting that everything must have opposable thumbs, because we do. Of course we know that to be very false, but the only reason your statement is not immediately similarly absurd is because you're referencing things that cannot be directly observed.
