We can easily find the answer to the question of how living beings originated in the fossil record. The oldest fossils of complex living creatures are found is the stratum of the Cambrian era, which has an estimated age of 520-530 million years.
The fossils found in the Cambrian rocks belonged to snails, trilobites, sponges, earthworms, jellyfish, marine crustaceans and sea lilies. All of these invertebrates emerged suddenly and completely without previous ancestors, which is contrary to what the theory of evolution claims. This miraculous and sudden emergence of living beings is referred to as the "Cambrian Explosion" by scientists.
How such a great number of animal species could have emerged all of a sudden is a question that remains unanswered by evolutionists. An English biologist Richard Dawkins, one of the foremost advocates of evolutionist thought in the world, comments on this as follows:
For example the Cambrian strata of rocks, vintage about 600 million years, are the oldest ones in which we find most of the major invertebrate groups. And we find many of them already in an advanced state of evolution, the very first time they appear. It is as though they were just planted there, without any evolutionary history. Needless to say, this appearance of sudden planting has delighted creationists. (Richard Dawkins, The Blind Watchmaker, London:W. W. Norton 1986, p. 229.)
As Dawkins, who is an evolutionist, is forced to acknowledge, the Cambrian Explosion is strong evidence for creation.
