My opinion on this are not well finalise yet.
To me, the neurons and synapses connecting are just one part of it. There is more to just chemical reaction.
There is a non-biological element to it, perhaps somewhat metaphysical, or even spiritual part of it.
Instinct, Intuition, imagination, there is more than just “data processing” from our sensory.
Or maybe I am “over-thinking” this 😅
