Respectfully. It's obvious that you don't know the difference between observation and experiment. Experiments are used to test hypothesis, not observations. Personhood can and has been modeled mathematically.
" Not all knowledge is obtainable or verifiable by the scientific method."
If it can be observed at all, it can be. If it can't be observed, it's likely not worth anything, other than as fiction. God knows this. That's why He came to teach who He is and what He is about.
Do you consider the late Francis Crick to have been a scientist capable of observation?

If God and spirit are anything, they are transcendent - transcending pure empirical science and reason/logic.
If you wish to reduce your religion to this, you have reduced God out of it.
