Evolutionists call the fourth from the bottom geological age layer the Paleozoic Geological Age. They say it is divided into several geological eras, and they call the first or the lowest of these the Cambrian Era, which they say was formed about 500 million years ago. I do not believe their timetable because of the many scientific evidences that prove the earth is very young. I present some of these in one of my books entitled Evolution in the Light of Scripture, Science and Sense . There are also many inconsistencies in the so-called geological ages timetable of the evolutionists.
Evolutionists say that what they call the Cambrian rock is the oldest rock with fossils in it.
Although the Cambrian explosion was once considered illusory, an artifact of poor fossil preservation in the Precambrian rocks, almost all paleontologists now agree that an extraordinary diversification of animal life occurred at the beginning of the Cambrian. There is little agreement on what may have triggered the Cambrian explosion, but there can be no dispute about its consequences. Virtually all basic multi-cellular animal designs evolved at this time, and the earth's oceans became stocked with them. It has been pointed out that the structure and order of the fossil record actually does not contain evidence that organic evolution has occurred. Furthermore, the fossils themselves certainly do not offer any evidence that organic evolution has occurred.
