Human Brain Still Changing?

[HydrogenBond]

I believe the brain via the unconscious mind does thought processing and synthessis in the background, which can become conscious later. If anyone has had kitten for a pet, even at six weeks old one will often see it practicing hunting, chasing imaginary prey around the house, even though it too young to have been taught, i.e., unconsious impulse that is teaching. As it gets older, it puts what its unconscious mind taught it through play impulse, into reality action. Humans from ancient eras probably learned the same way, i.e., unconscious synthesis and impulse leading to action (the workings of the gods), which is remembered and eventually done consciously and maybe handed down as tradition. For example, the gods gave humans fire, which was later handed down from generation to generation. I not equating gods with God. The estimate is that we use 10% of the brain? The 90% isn't brain dead but works in the background.
