But even if I didn't have a more compelling explanation, that doesn't mean I can't be highly critical of, or reach a conclusion that panpsychicism is highly unlikely to be approaching a good explanation.
For clarity: are all the things you've said above your opinion, or are you presenting then as facts (which was my interpretation)?
But also, see the rest of my comment. The onus is not on me to arrive with a better explanation just because there's a bad explanation on the table.
If I come home and find a cookie on my counter, and someone said "I think that a space alien teleported the cookie there" and I said "I think that's unlikely to be the correct explanation." And then that person asked "Well, what's a better explanation?" and I said "Maybe someone broke into my apartment, felt guilty, and left a cookie there." and then grilled me on that counter-explanation.
So far I don’t think you’ve shared a better one, and I don’t think you think you have either.
If you try it and end up somewhere else, let me know! I’d be genuinely interested to hear about it.
My conclusion is that panpsychism is god of the gaps for consciousness right now.
