Why atheism always has a burden of proof

[Sword of Christ]

Those images show that different areas of the brain are more active when performing different actions.

The observable reaction to these actions being different to just normal talking or being a relaxed state or whatever. So you can least demonstrate that is a function of some kind there to accompany the experience they aren't simply live action roleplaying. You can't prove it's God though.

This isn't anything surprising and it's certainly not indicative of a "spiritual state." Researchers continue to study the brain and as far as I am aware have mapped out regions of activity and regions that perform different tasks. It stands to reason that brain activity would change depending on what we're doing and thinking.

Of course and prayer demonstrates a real physical effect on the brain. Something consciousness itself is doing to the brain in this case. I don't think you could do something like this if as like you believe it is merely a byproduct or secretion of the brain itself. You can see the the relationship between conscious and matter goes both ways.

How is any of that indicative of a "spiritual state"?

People involved claim to be having one and we have a look their brain while they're at it so that's the brain state of someone having an encounter with God, if that's what it is you can't prove anything beyond what you can see and detect.
