In the sense that you are asking, I can't answer this question, because I don't know. Perhaps ants and up have it? idk, there is no way to know. There is no way to even know if other people definitely HAVE consciousness, I take it on faith. I can only KNOW for sure that I have consciousness. How do I know that? Because I am conscious of it. Is this circular? Yes. In fact, this is the ONLY absolute reality that I can positively assert, without reference to any other fact or axiom. The fact that I can think, or that I have a body, or that it's day outside, all of these first need me to be conscious. So, yes, it's circular, and it's true, and you know it's true that you are conscious. And you don't need process any information to know that you are conscious. It's prior to all that.
