The Cambrian Explosion of Life and the Geologic Record
Mainstream scientists have insisted that life has gradually emerged on Earth from simple cellular organisms to more complex multicellular forms of life over vast eons of time over 4.6 billion years. However, the simple fact is that the geologic record that we observe today does not show evidence of a gradual emergence of life over billions of years but rather of complex forms of life appearing suddenly in the strata with no evidence or trace of simpler forms. The greatest example of this is known as the Cambrian Explosion, which refers to the appearance of a large and diverse collection of compex collection of fossilized life forms that appear suddenly within the stratigraphic layer known as the Cambrian. The sedimentary rock layers observed on Earth today are divided into two main groups by mainstream scientists, the oldest of which is known as the Pre-Cambrian layer and is claimed to have been deposited from 4.6 billion years ago until about 545 million years ago. The other layer rests on top of this Pre-Cambrian layer and is known as the Cambrian, and is claimed to contain sediments deposited around 545 million years ago. On top of the Cambrian layer are more strata layers that are claimed to be younger and have been deposited since 545 million years ago until today. In addition, many forms of complex life appear suddenly within the Cambrian layer, a fact that gives many problems to the concept of macro-evolution of life over millions and billions of years of time.
The complex life forms found suddenly within the Cambrian layer include various forms of molluscs, brachiopods and other complex shelled organisms, marine reefs, the Ediacaran biota, and arthropods such as trilobites and crustaceans. In addition to the sudden appearance of so many complex life forms within the Cambrian layer, mainstream scientists have difficulty explaining what event could have caused such massive death on Earth so suddenly as observed in this layer. Evolutionists propose many possible types of mass extinction events to attempt to account for this event with great difficulty. Many creationists recognize this Pre-Cambrian-Cambrian layer as the result of the catastrophic year-long Genesis Flood, which creationists believe occurred not 545 million years ago but within a mere 5,000 years ago. All of the strata above the Cambrian layer were deposited during the year long Flood, according to creationists, and this description is in contrast with the mainstream science claim of multiple mass-extinction events over a half-billion years. Mainstream scientists propose a variety of possible causes for the multiple proposed mass extinction events, including a variety of environmental conditions, yet these scientists deny the possibility of a global flood despite over 71 percent of the Earth being covered by water today.
