Why do some creationists claim marine fossils on mountain tops prove a global flood?

yeah, well, good luck with that one. people believe what they want to believe when it comes to the whole god and creation thing versus evolution and long time. Generally speaking, it has been my experience that people who think a flood placed fossils on mountains have never been on a mountain where those fossils are found. Really isn't much about the fossiliferous rocks in the mountains that makes one think of a flood origin. it isn't a deposit of fossils on the mountain, the mountain IS that rock,
