Quite a lot of other animal species have self awareness too, by the way.
You can't be certain of this unless you can enter the mind of the animal. All you can say is that they appear to have self awareness. It would be possible for humans to construct animal like robots which appear to have self awareness, but they would just be man made machines.
same for all humanity too, but you use the method of similarity to establish that and then inconsistenlyand biologically abandon it for other animals.
But animals are seen to behave in a much more predictable manner than humans. Also humans can attach meaning to what they perceive, not just react to it.
The first part is irrelevant, the second part an assertion.
The method you are using to attach the concept of perception to other humans would work for other animals (btw we are animals and you use of the term as of we are not is illustrative of an incorrect assumption that is part of the inconsistency of your position).
If you use the method to make the statement for humans about perceptuon, not using it for other animals is illogical and inconsistent. Try again.
