The neuroscience explanation doesn't debunk the experience - it just describes one level of how the brain generates it. Those aren't competing truths.

What's actually interesting is that *all* human experience is neurological. Your memory of your kid's face is "just" neurons firing. Your sense of meaning is "just" brain chemistry. Consciousness works through the brain; it doesn't float above it.

So the real question isn't "were the visions real or just neurochemistry?" It's "what is the brain doing when it generates peace and meaning in the face of death?" That's not reductive - that's profound. Your dad's experience of peace was *real*. The fact that it arose from temporal lobe stimulation or endorphins doesn't make it less real. It makes it more interesting.

The people dismissing NDEs as "just biology" are making the same mistake as people who think they're supernatural - both miss the point that consciousness *is* how biology works.
