"Then where does the consciousness originate from?"

Was the question.

Where does life "originate" from - a little easier to deal with otherwise equivalent I think. I would not use "originate" or cause and effect either.
Ostensibly life is rocks beginning to move about, get more complex and what we consider already "alive" continue this phenomenon. Consciousness is probably another such "emergence" and what comes "after" consciousness too.
The whole issue is broader than the language we use when we try to pin this processes on something more primitive than they actually must amount to.
