Evolutionists often advocate the belief that ancient man was intellectually inferior to modern-man. The theory, however, does not fit the facts. While there are numerous theories on how megalithic structures like the pyramids were built, there continue to be arguments over the technology used to construct them. In addition to this, ancient pyramids have been found in various places around the world. Then there are the 2,000 year old batteries known as the Baghdad Batteries, which date back to between 248 B.C. and 226 A.D. It is believed that this ancient battery might have been used for electroplating objects with gold.
An interesting artifact was recovered by sponge-divers from a shipwreck in 1900 off the coast of Antikythera, a small island that lies northwest of Crete. The divers brought up a hunk of corroded bronze that contained some kind of mechanism composed of many gears and wheels. Writing on the case indicated that it was made in 80 B.C. An x-ray of the mechanism revealed it to be very complex, containing a sophisticated system of differential gears. Gearing of this complexity was not known to have existed until 1575!
There is ample evidence of brain surgery, dating back to the Neolithic (late Stone Age) period. The unearthed remains of successful brain operations, as well as surgical implements, have been found in France. Pre-Incan civilization used brain surgery as an extensive practice as early as 2,000 B.C. In Paracas, Peru, archeological evidence indicates that brain surgery was used extensively. Here, too, an inordinate success rate was noted as patients were restored to health.
Consider the work of Heron (or Hero) of Alexandria who lived in the first-century A.D., probably from A.D. 10 to 75. He was a mathematician and practical inventor. He invented a sacrificial vessel where water flows only when money is dropped in a slot. Heron also constructed a small temple so that when a fire was lit, the doors opened spontaneously and shut again when the fire was extinguished. These devices were designed, most probably at the behest of the king, to make people believe that the gods were real and near. Heron also developed elaborate entertainment devices that set wooden actors and props in motion without any of the pulleys and weights visible to the audience. He is most famous for inventing the aeolipile, the precursor to the steam engine.
