I dunno—you set out to prove something about some battle recorded in the Bible, or whatever, you're gonna end up uncovering some real history (maybe even the kind you wanted!) probably, so there's a substantial connection to reality to drive the overall process, even if there's strong bias in the mission. The evolution (har, har) of that into something like a secular museum has a clear path to follow.

You set out to prove the Earth was made in 6 days a few thousand years ago, you're... likely not gonna be coming up with much that's connected to reality, even by accident.

Though it is funny to imagine.
