Logic tells me God doesn't exist but my heart says otherwise.

Those effects and their mechanisms are a fit subject for science. Each person's internal, irreproducible experience, however, is not.

How is that so? On what basis are you asserting that science cannot record these internal, perhaps "irreproducible" (though I don't see why this necessarily be the case) experiences, in search of underlying psychological principles and their mechanistic correlates?

They are internal, not accessible as objective facts.
