Many molecules necessary for life, such as DNA, RNA, and proteins, are incredibly complex—so complex that claims they have evolved are absurd. Furthermore, those claims lack experimental support.a
There is no reason to believe that mutations or any natural process could ever produce any new organs—especially those as complex as the eye,b ear, or brain.c For example, an adult human brain contains over 1014 (a hundred thousand billion) electrical connections,d more than all the soldered electrical connections in the world. The human heart, a ten-ounce pump that can operate without maintenance or lubrication for about 75 years, is another engineering marvel.e
