1.) The flood model where there was only ever one universal flood and no flooding ever since does not exist. It is a straw-man that keeps cropping up in this thread.
2.) There is no single scenario that can account for all polystrate fossils.
3.) Most polystrate fossils are indicators of rapid burial.
4.) That talkdeceptions article in the O.P. is lame even for them. They don't even get to tell lies about the issue because they never get around to what the issue is. Maybe they can pat themselves on the back for a 'lie of omission' - that's all I can figure.
5.) All fossils are polystrate vs. slow 'geology'. Any time they claim something like "each millimeter of depth in this rock represents 40,000 years" and that rock contains fossils - well, they're saying those bones stayed put out in the open for (meaurement in mm x 40k) years and fossilized.
6.) Combine 3 and 5 and see how much evidence there is everywhere for flooding. See how few places in the entire world even qualify as reasonable sites for slow deposition. Put two and two together.
7.) Or don't. If you're not convinced it's not because of the evidence. HEWG's been working his tail off; and me being lazy, I've given a concise summary. Shallow and deep have both been covered, so what's left?
