Is there any real evidence of Biblical events? For example, some might mention the Shroud of Turin and the evidence for it. But others would counter this by pointing to the carbon dating results, which were supposed to show that the Shroud was too young to have been the burial shroud of Christ. Nevertheless, there are those who question those dating results. One is Professor Garza-Valdes, who created a brand new science after the carbon dating of the Shroud. (It's called archaeomicrobiology.)
Garza-Valdes found that the dating of a jade object, by carbon-dating blood on it, was skewed by the presence of a coating formed on the jade by bacteria. Of course, this bacterial coating contained organic material, which, of course, contains carbon, and being of a younger age than the original object, threw the date off. Garza-Valdes believes this same type of bacterial coating could account for an erroneously young dating of the Shroud. A coating of this type could cause an old piece of linen to be dated much younger than it really is. He has written a book about this, entitled The DNA of God.
