That same question can be asked of Manehivi (1940-41), Neloaig (1943), and Iokaeye (1947) Anthropologists generally put the origin of the John Frum cult in the 1930s so where are missionary writings regarding John Frum from
that time, O Wise One?
Never mind have one letter written in 1947 putting John Frum even earlier (1910s) compounding the issue.
As I pointed out if we take the claims of NT manuscript being among the DSS-Qumran finds seriously (stop ROTFLOL, you'll hurt yourself

) then the limitations of paleographic dating give you
a 50 year range as a minimum allowing many of the finds to predate Jesus never mind Paul's conversion.
As I have said the dating of the Gospels before 130 CE requires unknown methodology in terms of quality or reason. In fact we are
still waiting on that scholar history paper that shows these guys simply aren't doing a Bermuda Triangle and just repeating what the previous scholar claimed.
