Do you believe there's such a thing as electromagnetic fields?
Well, if you do, explain to me how you would know there's an electromagnetic field precisely where there would be nothing for us to observe as being somehow affected by it?
Same for all physical fields we know of.

That's absurd. You have no idea. I pointed out that electrical activity in the brain is detectable in an active brain and the detected patterns have been used to predict decisions before they become conscious. Which relates patterns of neuronal activity/firings to specific decisions and thoughts, this option over that option, etc.
For example:
''When it comes to making decisions, it seems that the conscious mind is the last to know.
We already had evidence that it is possible to detect brain activity associated with movement before someone is aware of making a decision to move. Work presented this week at the British Neuroscience Association (BNA) conference in London not only extends it to abstract decisions, but suggests that it might even be possible to pre-emptively reverse a decision before a person realises they’ve made it.
In 2011, Gabriel Kreiman of Harvard University measured the activity of individual neurons in 12 people with epilepsy, using electrodes already implanted into their brain to help identify the source of their seizures. The volunteers took part in the “Libet” experiment, in which they press a button whenever they like and remember the position of a second hand on a clock at the moment of decision.
Kreiman discovered that electrical activity in the supplementary motor area, involved in initiating movement, and in the anterior cingulate cortex, which controls attention and motivation, appeared up to 5 seconds before a volunteer was aware of deciding to press the button (Neuron, doi.org/btkcpz). This backed up earlier fMRI studies by John-Dylan Haynes of the Bernstein Center for Computational Neuroscience in Berlin, Germany, that had traced the origins of decisions to the prefrontal cortex a whopping 10 seconds before awareness (Nature Neuroscience, doi.org/cs3rzv).''
