Questions on the origin of life and of the universe must have challenged human curiosity and imagination as soon as early man had time for activities other than survival. In 1859, Charles Darwin published the Origin of Species, and since then, people have debated between the creationism and evolutionism theories. The theory of evolution has been supported only through various religious writings, particularly the Bible.
Creationists believe in a divine creator, God. Creationism has a broad range of beliefs involving a reliance on God's miraculous work to explain the origin of the universe, of life, and of the different kinds of plants and animals on Earth. According to the creationist view, God willed everything into existence, and this is how humans came onto the Earth. Creationists say that the evolution theory is biased and incomplete. They believe that the fossil records fail to provide a link between diverse groups. To find out how old fossils are, scientists use a method called radioisotope dating, which measures the amount of uranium or lead lost over the years. Creationists deny evidence from this testing because they assume no uranium or lead has been lost over the years. .
The process of evolution, which all living things developed from unicellular organisms, over billions of years Exactly how evolution occurs is still debated but it is a scientific fact that it does occur. Most biologists believe that the modern theory of evolution arose from a history of mutations either physically or chemically and it is still occurring. All organisms can be traced back to a common ancestor from inanimate matter.
The science of paleontology or the study of life provides the most direct proof of evolution in the past through fossil remains or impressions, usually in rock. Other evidence comes from comparative studies of living animals and plants, including their structure and geographical locations.
