The spiritually blind (it is a blindness of the mind) are spiritually deaf too. They do not understand.
You're assuming the premise in the conclusion. That's a giant error on your part. You cannot explain spirit, spirituality, what it is, how we can objectively determine if it exists, detect it, etc. You've done nothing but claim it exists and then proceed from there. You've given no reason for anyone to think you done anything.
You have all your work ahead of you.
Not only did I look at the experiment, but I also observed, understood and concluded.
That has nothing to do with this. A blind person could also perform that experiment. I've no idea why you brought that up.
God's Holy Spirit is "empirical" evidence of God
If you can't show or otherwise demonstrate it to me, then it's not empirical in any way, quotation marks or not. You apparently need to re-take that physics class to learn what empirical evidence is.
