I'm not sure why you've been downvoted for this. The fact that our consciousness is nothing more than the emergent behaviour of various ongoing chemical and electrical processes doesn't sit well with some people, I guess. Personally I derive a lot of comfort from the fact that we aren't "special".
I use my consciousness to infer a physical reality, which I then use to further infer that consciousness doesn't actually exist. That doesn't strike me as great reasoning. Certainly far from "fact."
