Facts:

1.) We found titanium in 2 Bibles: (JG and B-36)

2.) Titanium in 15th century Vinland Map (purportedly)

Conclusion: B-36 must have been printed by JG and Vinland Map is from 15th century

Flaw:

Is it wrong for the stimulus to conclude the B-36 Bible must have been printed by JG because that assumes Titanium was rare enough so that it can be traced back to a specific printer? But I don't see what is wrong with using Titanium to prove VMap is authentic. Does VMap have any relationship with JG?
