All of this is at least intuitively easy to explain with added language and complexity in the brain. So like the chain would become:
Touch hot flame -> brain processes event (and then does complicated language processing, and complicated memory and emotion processing) and THEN sends signals to move hand or not move hand -> You experience all of this but it had no relevancy to the chain of events.
Where I would ponder the relevancy of consciousness is when it comes to attention and remembering things. Just from personal experience, I can read a book, watch a movie or listen to music and I will not remember a thing if I wasn't aware of it. Is awareness and consciousness the same thing? I don't know, but at least we are conscious of everything we are aware of, by definition, and not necessarily vice versa.
