Hi

Can anyone tell me how a thought is created\? How does an initial chemical reaction become what we know as a thought?

you are assuming some building-block approach to consciousness which is fallacious. See Searle 2000.

Can you prove my assumption is fallacious?

By the way I cannot prove it is true. My assumption is based on the fact that thoughts or rather types of thoughts can be altered by medication, like prozac.

the building-block approach is false because it provides no mechanism for binding of blocks, nor for supervenient relations within the system, whereas field theories of consciousness propose consciousness is a field that is modified and whose form determines or is isomorphic to our phenomenal conscious experience.

It is possible to follow any thought to it's source.
Since the nature of self is not bound to the chemical meat bag container and can experience itself outside of the meatbag container having thoughts, then the awareness may be influenced by the meatbag if it is made into the source through false belief and follows shifting fluctuations of the container.
