You have been talking about "conscious" and about "consciousness", as in being aware or awareness. That's different from thinking, learning or understanding.
Biologists, in particular neuroscience, have mapped out the brain functions as to what control what, what process what, and so on, especially those organs or tissues of nerves that provide senses to human, as well as other animals.
And as I am not a biologist or neurologist, I am only focusing on consciousness in general, as to which living organisms are conscious, and which are not.
What I have learned is that all vertebrates are conscious. As humans are tetrapod vertebrates, humans have something in common with other tetrapod vertebrates that provide then awareness through their senses, namely nervous systems:
- Central Nervous System (eg brain & spinal cord)
- and the sensory receptors, nerves in the tissues and organs that provided senses.
What the different parts (cortices, hence sensory cortex) of the brains do, is process those sensory information that the sensory receptors have picked up.
For invertebrates, many have nervous systems (eg brains) as well as sensory functions, but there are others that don't, instead their nervous systems would be either nerve rings or nerve nets, which provided either full or limited consciousness.
Then there are plants, fungi, protists, bacteria & archaea that have no consciousness at all, but they are alive or they have potential to reproduce. So consciousness play no part for these living organisms.
Those are the fact, biological facts.
What you have, are not facts, but your own personal opinion, belief, worldview, or whatever you want to call it.
You can meditate & still your mind, all you want, none of that provide any insight about the natural world, let alone about the Universe.
So if humans are conscious because of their nervous systems, then why would there need to be a "precursor"?
If you think there is a precursor, that's what you are claiming, then it is up to either show evidence or demonstrate it. Something that you cannot do, except to conceptualise. Your concept of conscious is nothing more than just opinions. The Universe being conscious is one of those opinions you have.
