IMHO, yours is one of the closest to get it right.
The same question is essentially what Adam performed in the Garden of Eden, naming all the animals. The action of naming, was more than simply identifying a verbal expression with an object. Rather, the name is an expression of the essence of the object/subject being named.
When Adam had body, soul, and spirit, and presented with other living beings which had body and soul, but lacking the spirit, which presented humans as having been made in His image, Adam was able to then discern between the animals and God in fellowship with Him.
I have a problem believing in things I can't see. But I'm not alone.
When something hits me in the head- and I didn't see it?- I respect it. Ask anyone over 6 feet tall (come to think of it, my foot is at least a foot long- now that you mention feet) how many times they've been smacked in the head. Ever have a car drive over your foot? Hurts like hell. If a way exists to utilize another 'sense' it should be discovered. Otherwise, we'll look like dummies to those 'in-the-know'.
