Sediments, Fossils, and Noah'Flood. NOT!
When Noah's flood occurred, the Scriptures say the waters of the flood covered the tops of the mountains, so the present-day mountains already existed:
"And the waters prevailed, and were increased greatly upon the earth; and the ark went upon the face of the waters. And the waters prevailed exceedingly upon the earth; and all the high hills, that [were] under the whole heaven, were covered. Fifteen cubits upward did the waters prevail; and the mountains were covered."
(Gen 7:18-20 KJV)
Geologic Fact: Portions of most of the Earth's mountain ranges are composed of sedimentary strata or metamorphosed sediments which contain fossils (the evidence of living creatures long since dead and buried). Three examples are the Appalachian mountain range of the eastern United States (one of the older ones), the Alps of Europe and the Himalayas (one of the younger ones). The sedimentary layers that were uplifted to form these great mountain ranges are many thousands of feet thick in places and well above sea level today. In many places, especially in the older Appalachian range, angular unconformities abound, showing where ancient sediments have been tilted and partially eroded, with newer more horizontal sediments being deposited atop the tilted erosion contact surface.
If these mountains existed before Noah's flood (which the Bible says they did), and these mountains were formed from uplifted sediments containing fossils (go climb a mountain and see them with your own eyes), then the creatures that these fossils came from all died sometime long BEFORE the great flood.
