Logic vs Evidence

[Fidel_Castronaut]

There's poor logic and evidence has different value depending on source. How reliable for instance is written historical accounts?

Depends on the context and the corroborating/contradictory source material of that context, be it primary or secondary evidence.

Eg (as a cheap shot) the global flood. Bracketing out the impossibility of it, there is no geological data to suggest it ever happened, leaving only the bible as the source for that christian variant of a probably more accurate localized flood of ancient times.
