From the OP:
...
Most of history is backed up by the following:
1. Many independent historical reports reported by clearly unbiased people.
This is a huge claim.
That ain't nothing. I once claimed I was at the bingo hall all night, only to find out that'n that's now an ex done saw me down to the motel. She set a bias on me like y'all ain't ever saw.
(two edits to get the following words down right)
It's hardly fantastical to seek multiple, unbiased reports in order to form an opinion on a notion or more.
(/edit)
A claim presuming knowledge.
It doesn't so much presume knowledge, as it displays a good bunch of it.
What are we to do, expect a few biased historical records, or a bunch of unbiased ones of 'em?
So then,
Many? How many? Which? What report has zero, ZERO bias?
Here's just one:
I ain't allowed out the house no more, cause it is, I see and hear stuff that ain't there.
Notice here there's little reason to conclude I'm biased, when it is, I'm the one can't enjoy gardening, or brewing, or just taking a leak off the deck.
There's nothing magical about my claim, so it can be considered with a high degree of reliability - while maintaining a healthy skepticism on if maybe I ain't snuck me out a time or two.
Who here has even read, in full, Josephus, and read even a single book by an historian on Josephus?
I ain't.
I react to claims folks present, far more'n the writings of the ancients (as this is debate and all).
Who here has read a single primary source for Alexander the Great, and asked of it daunting questions about their reliability, and found satisfying answers to these questios?
I'm just not finding a great bunch that wants to blow up stuff, kill people, restrict the rights of people, or who fret over which bathroom it is folks use, who say they only do such cause it is, ol' Al there told 'em we'd all be in trouble for it.
Who here puts faith in their history books, and does not doubt the claims there made because most of them do not include the miraculous, and do not make any claims on their lives?
The scientifically minded will doubt even their own pet notions - if only so's they can pride themselves on being scientifical about it.
Conclusions?
I see little reason to fret claims that have no basis in reality - 'cept when such claims lead folks to trying to kill and blow up, and all that rights restricting.
If the angle presented here is such as "You believe that book, so it's irrational to NOT believe this'n", I say to such folks, "Don't care, long as you don't harm folks, or society, by acting on Mother Goose's orders!"
I might be Teddy Roosevelt, but I ain't.
