         | Science is not an exercise in accepting a scientist's say-so,
         | dammit. It's an exercise in producing and testing hypothesis.
         | For sciences that study the past it's harder to test because
         | you can't build a test, but you can still check that a
         | hypothesis is consistent with all the data available so far
         | _and_ any future new finds about the past.
         | 
         | In particular I find very compelling the theory that the YDIH
         | hit the laurentide ice sheet over Michigan, sending huge ice
         | boulders out that created the Carolina bays and essentially did
         | great damage, but with water ice, thus leaving very little
         | direct physical evidence -- no craters (apart from the Carolina
         | bays), no rocks out of place, no layer of material from the
         | impactor (because it was a comet rather than an asteroid).
         | 
         | Before sonar evidence showed that the continents must move,
         | geologists would say that the tectonics theory was debunked
         | (using whatever the appropriate term was then). Well here we
         | are now saying the exact opposite.
         | 
         | The only thing we can say with certainty right now is that we
         | don't have consensus as to the cause of the Younger Dryas _at
         | this time_. To say that the YDIH is debunked is not true and
         | not helpful.

         | have caused _some_ extinctions, and there was a long tail of
         | megafauna extinctions that extended long after the younger

         | https://en.wikipedia.org/wiki/Doedicurus apparently didn't
