I'm disappointed, Juve. It seems that you are continually growing farther and farther from your geologic educational roots. It used to be that your biggest fault was that you were non-committal when it came to dating the age of the earth. Which is fair enough. You didn't want to pin a number. Now, you are arguing about shale being part of the flood deposit, when you KNOW that it goes against everything that geology teaches.
You mentioned that the flood would have left plenty of fine sediment to settle and become shale. Well, yes, but there are MANY layers which we find ON TOP OF and IN BETWEEN shale layers in the geologic record.
Shale is one of many smoking guns in favor of flood-deniers, including evaporites, paleosols, coccalithofores, and many others.
