"The idea that consciousness is an accident of evolution virtually destroys the concept of evolution"

Evolution is not an "accident". It is a scientific process. There is a great deal of misunderstanding about the nature of Evolution.

I would say that the notion of a god is a historical "accident". Dawkins calls it a "meme".
Consciousness and unconsciousness has to do with the function of the brain and studies
working with electrodes on the brain substantiate this.
