You suggest that our thoughts are the result of organised reactions
What do you propose could be the source responsible for this organising within an entirely material environment?
The development of a human brain is entirely in keeping with all physical laws as far as we are aware and is a product of evolution. And as all our thoughts are linked to electro-chemical activity within the brain, there is no need for any external non-natural(whatever that may mean) guidance to be involved.
Neuroplasticity is the brain's ability to reorganize itself by forming new neural connections. New information and experiences can lead to the brain organizing neural pathways. This process starts when we are babies and continues for the rest of our lives, although, as we age, it becomes less. So the pathways that our brains create, especially as a child, is the foundation of our thinking throughout our lives.
Now I would suggest it's time for you to answer the question that I asked you in post 49263 and to which you still have not responded:
'If you think differently, why not produce the evidence to support your conclusions?'
