I didn't say the soul pulls energy from the person, but there has to be interaction between material and spirit (I don't need spirit to be its own manifold in this model so I didn't presume it)

If the soul doesn't interact with the material then there's no connection between the two and theyre not associated.

So we should be able to detect that interaction. It should have enough of a footprint that were able to notice something even if only side channel effects (which is how we discovered radiation and the heating properties of microwaves).

And we haven't.

As I said, it doesn't rule out spirit, but like many apologetic arguments, it takes a lot of weird presumptions to assert that spirit does exist, does interact with material, yet cannot be detected with the scientific means we have in the twenty first century. It can happen but then it requires stark changes in the models of mechanics we have (such as possibly the simulated-universe hypothesis). In this case our scopes are good enough to see the proverbial teapot. 🫖

But I appreciate that it's difficult to comprehend what the issues are, and why this is a failing not merely of Christianity but any narrative that involves spirit or afterlife. It rules out most models of ghost and fairy phenomena as well.

And don't worry. If you don't get it today, we'll have many (hypothetical, thankfully) days together in the break room so that I can assure you do.
