This has been an interesting thread but an important point has been missed.
It's clear that some theories describing an evolution of the solar system over ~ 5x10^9
years which predicted a lot of moon dust were wrong because there isn't lots of dust.
But YEC theories contribute nothing at all to the matter because they make no prediction
about the amount of moon dust to be found. If we _had_ found lots of dust, YECs could
have simply said "It was created that way 6000 years ago."
This is the way it often works out. E.g., YECs sometimes say "Evolution
predicts a continuous range of organisms between taxa & special creation doesn't, so the
lack of fossil transitional forms favors special creation." But it does no such thing
because species _could_ have been created 6000 years ago with gradations as close to
continuity as you wish. The YEC view in itself requires no unique prediction.
I.e., if the YEC view isn't scientifically vacuous, it's pretty close to it.
