Why would older rocks be less resistant to erosion?
While it's always a bit of a walk on the wild side trying to guess what Faith might be thinking, I'm going to hazard a guess. My guess is that when she looks at a cross section of strata exposed in a canyon or elsewhere, she momentarily forgets that the layers have been buried for most of their history. It's then just a short step to receiving the intuitively divined certain knowledge that the really old layers should have weathered more than the younger layers, despite their not actually having been out in the weather the whole time.
The thing is nobody knows exactly what the pre-Flood terrain was like.
This would have been a good place to stop.
Following that line with a series of descriptions of the "pre-Flood" world - using words like "probably" and "likelihood" - tends to reinforce the already stunningly obvious reality that pretty much everything you say is pulled directly out of your butt, with no justification other than rhetorical convenience, and with no regard to what you have said elsewhere.
Why shouldn't they? If they were contemporaneous, and all the strata were formed by the same event, they should be mixed together. If it was just blind luck that determined which organisms got lumped together in any particular spot, why would we see the consistency that we do in different geographic locales?
Coragyps' question is clear and straightforward. If other organisms are found together in the same rocks, why aren't the ones he mentioned?
If a few days of local rain can collapse a thickly forested mountainside, then a worldwide downpour for forty days should collapse a few million times that, and why wouldn't it all become suspended in the flood water as it rises?
I'm going to go with "gravity" on this one. You have noticed that some layers that aren't on the bottom contain rocks, right?
Re: Evidence for horizontal deposition of sediments
The simple fact that rocks lie all over beaches everywhere without sand draping over them.
Do you really, honestly, not understand the difference between a beach environment and the bottom of a body of water where there are no waves? You've seen snow drape over objects during a heavy snowfall on a calm day, right? Does the fact that snow doesn't drape smoothly over a mountain peak in a blizzard mean that those calm snowfalls don't happen?
Turns out it was really rather a simple problem caused by people who are aware of the procedures of road-cut blasting not realizing that someone unfamiliar with them would read "holes" as something you see from the front.
Do you see any parallels between this situation and your relationship to geology in general?
