If everything has a purpose then evil doesn't exist

[Mister Agenda]

History is not a falsifiable science. History is largely based on eye witness testimony and period documentation. As there isn't an experiment we can do to independently verify whether or not Columbus sailed in 1492. The evidence we have comes from eye witnesses and period documentation. So unless you are saying falsifiable science is now accepting eyewitness testimony as scientific proof, then history and science are two different intellectual disciplines with two different rule sets. Just like theology is an independent discipline who like history does not need to obey the rules of 'science' to be vetted/verified.
