Greenland

During one Ken Ham's rebuttals he gave an example of a World War Two plane that chrased on Greenland that had been found 70 years later, 200 ft beneath the snow and 3 miles away from its original crash site as evidence to his claim that our use of geographical indicators such layers in ice and the ground are incorrect. This is really random but I read the book written by one of the people who found the plane in 2009. It is call Frozen in Time, it is very good and I highly recommend it. Do you know how those looking for the plane knew where to look for the plane?  Using geological information gained from the study of movements in the layers of ice on Greenland, which really just one large glacier. The entire time Ham spends trying to prove the Bible correct he is quoting examples from the Bible as evidence, I don not understand how he still believes what he believes. I know people who are very religious, who go to church every Sunday, but I did not know people like him existed. It is very unsettling.
