A way around the nomenclature problems is to try and look at experiments instead. For example Turing seeming frustrated by similar discussions on will machines be able to think that turned on how people defined 'think' and instead proposed his experiment where you can see if people can tell the computer and a human apart by asking questions by text.

I'm not quite sure how you'd apply that to consciousness vs thinking say.

Thinking about it consciousness no doubt got there through evolution, as did other aspects of animal life, and functionally, if you think about something like a deer, it increases its survivability to be aware of what's going on, where it is, if there's a predator near, should it run away etc. The inputs are billions of sensory and memory neurons and that info has to be filtered down to something like a situation summary so other parts of the brain can make a decision like whether to stay eating or run. I presume consciousness is basically the situation summary.
