Max Hahn and his wife Emma were on a stroll in June of 1936 when they came across a rock with a piece of wood sticking out of its center. They took the peculiar item home and later opened it with a hammer and chisel. Strangely, what they discovered inside resembled a hammer from the ancient world. After handing it over to a group of archaeologists for examination, they learned that the rock casing the hammer dated back more than 400 million years to the Ordovician period!

The accuracy of that dating has been called into question, but here's the kicker: preliminary estimations put the age of the hammer at more than 500 million years. The handle is so ancient that it has already begun to coalify in places. It didn't take long for creationists to jump on this, and in the 1980s, creationist Carl Baugh used the hammer as a springboard for his conjecture about how the Earth's atmosphere before the flood would have fostered the development of giants. The iron used to make the hammer's head is purer than anything nature could produce without human intervention.
