The term, "stone age" is deeply imbedded in our language. Yet, it only illustrates how thoroughly the evolution world view permeates our thinking. The term evolves from the idea that there was a time in man's history when he was so primitive that stone tools were all he knew how to manufacture.
The current Creation magazine, published by Answers In Genesis, discusses the history of the term and the view that there were three stages in the evolution of man's advancement: the stone age, the bronze age and the iron age. It seems that the "three-age system" was invented by a coin collector, Christian Thompson, who was appointed as the first head of the Danish National Museum.
The museum contained piles of "prehistoric" tools, weapons, and other artifacts. Thompson's job was to bring some order out of the chaos. So, he decided to classify every thing by its material. He presumed that, if man evolved, his first tools and weapons would have been rocks that he picked up.
Since bronze, or brass, was easier to work, he assumed that its invention would have been next, followed by crude iron implements. Archeologists admit, however, that all three types of tools are found together in archeological digs. The concept so neatly fit the larger erroneous assumption of evolution, that the "stone age man" dressed in skins and carrying a big club, is a popular image in our children's serious history books.
Again we only need to turn to the Bible for perspective. In Genesis 4:22, Tubalcain was "an instructor of every artificer in brass and iron." This was before the flood.
Thus we see that the "ages" of man is just another popular idea with no basis in fact. One by one, the "proofs" of evolution are disappearing. Author Thomas Heinze has written a book on The Vanishing Proofs of Evolution. In it he details the myths supporting the evolution world view and shows how none rely on reasoned fact. All the facts point to a Designer whom we know as Jesus Christ.
