You are quite right that the rock layers are made by the violent flood and the "breaking up of the waters of the deep."  
- Most fossils are either marine fossils or land and marine fossils mixed together.  This makes much more sense if the layers were caused by a global flood.
- Most animals don't become fossils when they die.  For fossils to form, it requires the animal to be buried quickly (so not even bacteria can break them down) and to be exposed to mineralized water (like sea water or volcanic water).
-  There are lots of places that sedimentary rocks were significantly bent (even 90 degrees or more) without cracking.  If they were soft mud at the time, this makes sense.  If they were lithified, they would crack.  Frequently people will say they bent because of heat, but heat metamorphizes the rocks and that hasn't happened.  These rocks layers were clearly bent while wet.
- When "scientists" say the rocks were formed over millions and billions of years, they will point to "gaps" in the rock layers.  They will point to a knife thin border between rock layers and claim there are millions of years missing, but this is nonsensical.  If millions of years have gone by, you would expect to see erosion, with gullies and even valleys, but you see perfectly flat, even borders between layers.  You don't even see animal or insect burrows.  The most likely explanation is that the layers were laid down only hours or days later, not the purported millions of years.
