Your identity is inside your brain, I agree. Your emotions are inside your brain. You can call them spirit(s), no issues.
But do you believe spirits exist outside of your brain? What are they made of?
Where is the Holy Spirit, or any other spirit, other than human emotions located?
Forget your Christian mythology for a second, and think about the spirits, what are they and where are they right now?
Are they in our physical universe or outside of it?
If they are like God, residing outside of the known universe they are indistinguishable from things that do not exist such as fairies.
I think that this "spirit" idea is a fundamental concept of any religion.
Once you unpack that, the rest of the storyline falls apart like a house of cards.
So it was a serious question: what are the spirits made of and where do they live? And more specifically what is the Holy Spirit made of and where does he live?
How do you know that your mind or identity are inside your brain? You have been saying that science hasn't been able to even find these things, even though they are obvious. Think about the following, and apply it.
----------
Go to a railroad track somewhere, and get down and place your ear on the track. You can hear a train coming from great distances away. The track is solid, but you can hear the train farther away than you can hear it through the air. In other words, sound travels through solids.
Same with under water. Sounds that you hear underwater are different than the way you hear them through the air. But they are there, and sometimes even clearer.
Now don't jump into preconceived notions of what I am about to say next >>> Consider the aether that
notbatman talks about now and again. He talks about it, but doesn't ever really explain what it is. There isn't much explanation about it anywhere, except that some people think that it exists.
Next, consider the vibration aspect of electromagnetic waves moving through space. Sound uses material to vibrate through. What does electromagnetic vibration vibrate through? What is the medium that light waves use? Light is to what, as sound is to the material it vibrates through?
We call it empty space, because it seems empty to us. But the reason it seems empty, is that
our bodies are actually made up of subatomic particles/vibrations, electromagnetic energy waves traveling in circular motion, reacting off each other,
and off the medium that they are traveling through, right? So, everything is electromagnetic waves way down deep into the microcosm.
This means that there is a "substance" (that some people call the aether) that everything vibrates through, electromagnetically. We don't know much of anything about that substance. And the reason we don't is that it is a different
form of substance than the substance of complexly interacting electromagnetic waves that material is made up of.
And it seems that we are intentionally focused away from examining it... Einstein didn't have the training for the things he spouted, but they seem to work. So where did he get his ideas that seem to be so accurate? And why did he look away from the idea of explaining the aether when it seems that it would be a logical thing for electromagnetic waves to be traveling through?
Now, don't answer those questions... at least without considering the point, first.

The point is, we don't know, and seem to be shutting ourselves off from, the answers to your questions, of how the soul and emotions can exist outside of the brain. But we don't know that they don't. And we don't know that they can't. And the evidence that they might, lies in understanding that there might be a whole lot more to the medium that electromagnetic waves travel through, than is outwardly admitted in standard scientific circles.
Personally, I think the mind can work through the spirit and soul to manipulate the fabric of space, itself.
