The first life occurred ½ billion years ago during the Cambrian Period. These were simple organisms that evolved gradually from the ‘primordial’ cells.
The Facts Are .....
The 'Cambrian Explosion' is an evolutionary conundrum. Fossils of animals found in Cambrian rock assessed as 500-600 million years old seem to have appeared suddenly. They have no fossil ancestors, and they have no different body plans to animals existing today. Scientific American, November, 1992
It is not widely known among the general public, nor is it taught by educators, that Cambrian rocks actually contain complex life forms. Mostly, Darwinian philosophy rather than pure fact is presented by educators, in an effort to maintain the geologic column. Actually, even vertebrate fossil material has been discovered in Cambrian rocks. Barbara J. Stahl, "Vertebrate History: Problems in Evolution", Dover Publications: New York, 1985
"Finding vertebrate bone in Cambrian rocks, for instance, has proved that the backboned animals are as old as most of the known invertebrates." Written by evolutionary biologist Professor Barbara Stahl (St. Anselm College) in her book "Vertebrate History: Problems in Evolution", Dover Publications: New York, 1985 p:vii (4) An expedition to the Grand Canyon in October 1984 resulted in the discovery of numerous sets of fossil tracks. The tracks were believed to have been made by vertebrate animals and were found in sandstone, assessed as being 500-600 million years old. These tracks indicate that vertebrates were alive during the evolutionary Cambrian period, in total contradiction to evolutionary theory.

Fossil burrows have been found in the Frere Ranges, 120 km north of Wiloona (WA) in pre-Cambrian rocks. According to evolutionary theory, complex organisms had not evolved by the Pre-Cambrian period. West Australian, January 23, 1983
One thing the fossil record does
show is the huge imbalance between the variety of life in the
so-called Cambrian explosion (500 million years ago) and that following the great Permian extinction (200 million years ago). Palaeontologists note that all existing phyla were present as fossils in Cambrian rock, and that no new ones followed Permian extinction. This means that no new animal body plans have evolved for 500 million years. The fossil record therefore shows that macroevolution has not occurred as it was supposed to, according to evolutionary theory.

It is a widely held belief, and taught by educators as a fact, that as we dig down through the layers of rock, the fossils uncovered are much simpler, and more and more primitive. Examination of the best-known and most numerous examples of the Cambrian fossils (assessed at 500 million years old), which are found in the Burgess Shale of Canada's Yoho National Park, reveal the exact opposite.
Scientists have commented that these fossils are more diverse and just as highly-specialized as today's creatures. Some of the fossil molluscs have eyes which are as complex as the human eye, and the trilobite fossil's eyes have been described as "a marvel of optical engineering". Highline, 1990 (the official Yoho newsletter put out by the Environment Canada Parks Service)
"[Burgess Shale fossil Cambrian animals were] more diverse and no less highly-specialised than today's living creatures. Life today is less, not more, complicated than it was half a billion years ago".
