Well then what evidence is there which can not be adequately explained without consciousness?

Also just to make it clearer, I do not claim it to BE mythical. Just that it is easy to seem mythical.

It's an interesting misunderstanding isn't it, but natural in a way. For oneself to know or rather experience that there is consciousness and then to make the connection that similar creatures as oneself must have that same property feels just right, even logical. But the fact that there is no scientifically quality to quantify that observation makes consciousness quite naturally a rather mythical property.

I think your answer fundamentaly misunderstands consciousness. Though thats an understandable mistake to make.

I do not believe that there is any real evidence of what consciousness actually is and whether anything even has it (outside of yourself but that is different problem). To then claim you know what can NOT have consciousness is pretty naïve.
