In addition to just "wow", I'm curious what the argument behind that idea would be for this thread anyway, even if it weren't so self-contradictory. The issue of the order of the Gospels gives us two sequences to choose from:
Sequence 1:
- Lots of supernaturalness all over
- Books with much less of that
- Centuries of belief in the most supernatural version
...or, sequence 2:
- Books with the least supernaturalness
- More of it getting added to slightly later books
- Centuries of belief in the most supernatural version
While sequence 2 does point toward a mundane origin because there's a general progression from little to much, sequence 1 doesn't point toward any particular alternative because it has no particular progression. It just has a random low fluctuation between higher levels. With no progression at all but just patternless fluctuations at any time, the relationship between the actual original concept and the oldest books could just as well go either way, so this still doesn't yield an argument about what the original concept was like before it got written. (And that's
even if it were true.)
And worse yet, it doesn't do anything to get out of the fact that people normally just don't believe brand-new supernatural things that just got invented right in front of their faces. Some here have said that's the one origin all supernatural ideas have in common, but provided no reason to think that, and, when asked for it, even objected to that just like people who knew their bluff had been called. (They've also tried going back to the same couple of alleged examples over & over, which wouldn't have been enough to support their general claim that that's how it normally works in other cases in general,
even if they hadn't both been debunked.)
