The problem is that the Fossil record simply makes the Genisis account impossible.
If you have ever helped clean up after a flood, what you find is simply a mess.You find big and little critters, samples of anything that was in the way of the flood, all mixed together. If that was what happened, and then everything was buried as the flood subsided you should find a jumble of critters and everything else that was in the way of the flood, all mixed together.
It would be a very easy thing to spot. It would be all the junk and debry in the world, all compressed into one small band that was found all over the world and that looked the same all over the world. It would be a single small band of chaos between many much larger bands of order.
It would stand out like a neon sign. It would be impossible to miss.
But that is not what is seen.
You do not find dinosaurs and humans in the same layer. You do not find houses mixed in with dinosaurs. You do not find metal tools, finished wood, jewelery, and flowering plants mixed in with Dinosaurs.
You do find many, many layers. In most layers you do not find grass. In most layers you do not find ferns. In many layers you do not find dinosuars. In some layers you do not find land animals at all.
But the one thing that you DO find is that none of the layers show the typical signs of a great flood. You find signs of smaller regional floods. You find signs of long term climate change. You find signs of evolution, but no signs of a great flood.
