Creationism
If fossils were of animals drowned in the flood scientists think they would be mixed together. Christian creationists say this happened because of the Noahic Flood, and point to fossils of animals that died quickly. They offer many defenses. Some of these are:1. Fossils that were buried quickly, as in Lagerstätten. One fossil Creationists talk about is where one fish is eating another fish when it was buried.2. Polystrate fossils are fossils that go through multiple rock layers. Christian scientists say this can't happen if the rock layers were formed quickly3. Bent rock layers are rock layers that are bent in a way that Christian scientists say can not happen over millions of years. Christians say there are a lot of these.Other creationists believe God created everything between 13,000  and 14,000 million years ago.  This is called Old Earth Creationism.
