If I said that scientific theory was all perspective without right or wrong I'd get pilloried here, and with good reason.
Any interpretation of historical observations is analogous to a scientific theory like gravity. It may fit the observations or not, and we can use Occam's to winnow the likely from the unlikely. The only bummer is that observations are generally not reproducible as in the hard sciences.
apples and oranges. Sure that's true if you want to dwindle history down to just dates and events. The value of history(I assume for most) is in the meaning and lessons we extrapolate from it. You can argue it's an objective process when at its best but it isn't necessarily consistent across all perspectives.
