How does consciousness happen? Somehow in each of our 'CREATED' brains the combined activity of billions of 'CREATED' neurons each one a tiny biological machine is generating a conscious experience.

Watched it, and read many articles pertaining to consciousness, which are interesting, but IMO, it is only in observing the perceived physical realities that we can grasp the unseen spiritual true realities, and one of the erroneous claims by your chosen champions, appear to me, to suggest that consciousness ceases to exist when the body, of “skin, flesh, muscle, blood, bone, brain matter etc, etc,” has returned to the universal elements from which it was created.

What they fail to realise is that after the death of the body, there remains, a shadow or rather, a facsimile of YOU, the mind, spirit, or consciousness, that has been imprinted into the universal life force or soul, which returns to ‘THE GREAT THOUGHT,’ [The collective consciousness of all that exists] from which it will be resurrected in this cycle, or the next cycle of universal activity.

Unless of course that mind which is the potential child of the Logos, in whose presence no flesh and blood can exist, is aborted and suffers the second death and is separated from the eternal soul, which is the end of consciousness for that entity, after which there is nothing but everlasting total oblivion.

As spoken by your chosen expert, who said; "And when the end of consciousness comes there’s nothing to be afraid of, because there is nothing."
