@evanEvan Prodromou As far as I know, there is no evidence for the existence of a "spirit" in the sense of that word I'm familiar with, and so "spiritual" experiences by definition could not occur.
Even having a "never" option wouldn't be strong enough; the question feels like asking someone what age they were when they first flew on a broom. It's honestly really disconcerting to see a poll phrased like this and wonder where the disconnect in our realities is. I can't answer the poll.
