So the Lord said, “I will destroy man whom I have created from the face of the earth, both man and beast, creeping thing and birds of the air, for I am sorry that I have made them” (GENESIS 6:7).
Most people don’t realize there are actually very few fossils of vertebrates (animals that have backbones). Almost all of the fossils ever found have been marine organisms, snails, corals, plants, and insects. In order to become a fossil, a plant or animal needs to be quickly and completely buried. It seems that humans caught in this terrible Flood would try to save themselves any way possible. It is probable that as the Flood rose, humans continued to seek higher ground. As the humans and animals died, many would float and eventually sink—only to be washed away at the end of the Flood, when the mountains rose and the waters rushed off of the earth. Also, there were only two humans to start with—but lots of different animal kinds. So one would expect to find a lot more animal fossils than humans. However, there may be some human fossils somewhere in the world—after all, scientists have dug up very little of the fossil record.
