"The only problem with this belief is that is just that, it's a belief, because there is absolutely no evidence that human consciousness is "created" or "caused" by the neurochemical activity within the brain."

It is true that we don't fully understand the workings of the human mind, but recent progress is giving us great insights which support the notion that "human consciousness is "created" or "caused" by the neurochemical activity within the brain"

Here is a quote from the Mind Science Foundation.
In fact, technological advances in brain imaging have given scientists a new range of tools to more accurately observe and measure the apparent causes and manifestations of consciousness. fMRI (functional Magnetic Resonance Imaging) produces vivid images of the areas of the brain that respond to a variety of stimuli. Instead of trying to measure a purely subjective response, such as "that made me feel good," scientists can also see what part of the subject's brain is responding, for how long, and to what degree.

As a matter of curiosity, what other sources do you think could be responsible for human consciousness other than "".neurochemical activity within the brain"?
