Consider if there was no consciousness, matter and stars and life, but no consciousness, it is beyond comprehension,
If something isn't seen by consciousness, does it really exist? Quantum physics often suggests it doesn't! After all we know that it's not just the photon, but also the electron that acts as a wave, not just the electron but the atom, not just the atom but the molecule that acts in a state of superposition. Where does this end? Perhaps it only ends at consciousness, consciousness collapses the possibilities into a single reality. Think of it, can subatomic particles just by chance make atoms, atoms just by chance make chemicals/molecules, chemicals just by chance forms life, life just by chance forms a brain and consciousness, consciousness without which all of the rest would be a meaningless unacknowledged phenomena. If computation cannot explain the bringing forth of presence, awareness, then consciousness isn't made by matter. If consciousness isn't made by matter then there are two possibilities. Firstly, that consciousness and matter are two independent phenomena neither causing the other. Or secondly, that matter is manifested by consciousness. We seem to find some evidence for the latter phenomena, evidence that consciousness affects reality, this would seem unlikely or absurd if consciousness were a mere product of calculation. Indeed Quantum physics has found reliable evidence that consciousness can affect matter. Consciousness is similar to existence, you can't contemplate non-existence as if there were a period of non-existence there would be no experience of it, no times, no consciousness. In the same way, existence without consciousness is either absurd or at least without any possible value. So consciousness is as essential as exististance, consciousness is existence. Most (all) apparent unconsciousness is just a lower level of consciousness.
