You miss the point, Michael. Fine-grained material can be deposited in
high-energy environments, which David said was not possible and therefore
a problem for YEC.

Yeah, that's me, Michael, invincibly ignorant. Thank you for explaining
what a paraconformity is, I never knew. Now that we have cleared that
up, could you also explain: (A) if strata were deposited and eroded - how
did the eroded surface end up so flat, and (B) if strata were not
deposited in the first place, why do we not see evidence of weathering?
For example, in eastern Utah, over 200 km (SW-NE) of the Lynch, Muav,
Tapeats and Ignacio are conformably overlain by the Redwall and
Leadville. You're the one who said these arguments don't stand under
scrutiny; please, if you could get unbored for a few minutes, explain the
details of the mechanism for 200 km of planar erosion, or for protecting
strata exposed for 140 million years from chemical weathering and
