>I'm sure I have consciousness.

Why? How is your claim different than a Catholic who claims to have a soul? I respect their claim more than yours, oddly.

>I don't know how it works, i

How what works? This consciousness that you're sure you possess, but you can't measure, detect, define, or even really describe?

You don't have it. Everything you are can be explained without it, and it doesn't make you less than what you were if you had it. It's a nonsense idea, primitive and inherited from religion. You don't have it because there's no such thing.
