First, Rocam is a troll who likely isn't agreeing with me at all, but rather trying to delude me point by sounding like an idiot.
I did not put any weight of his point onto yours. I did however address both.
Yes, the written records are important. Nobody is denying that. The point being made for American slavery is that there are multiple independent accounts with a high degree of consistency. Those three factors - multiple, independent, and consistent - are very important in how much weight we give the written accounts.
What written records do we have that are independent of the Bible do we have exactly? If we have them, you should be able to reference them.
Again, a singular account for such major events, which supposedly spanned centuries, is not sufficient for reasonable belief. If I were to write an account of an entirely fictional major event, bury it in a sealed box somewhere, and historians find it a thousand years later do you think they'd believe it just because it was written? No, of course they wouldn't. Confirmation beyond a singular text is necessary.
That has no relevance to this discussion. It has zero bearing on the evidence.
The Biblical account clearly states that they were not being allowed to leave. This implies coercion, in other words forced servitude. If that does not constitute slavery then what does?
Again, not relevant to the actual evidence of whether or not it actually happened. Just because something is plausible doesn't mean it's true.
Exaggerations in the Biblical account are an important consideration. If they are indeed exaggerations then that means the account is tainted. This is why it important to have multiple independent sources with a degree of consistency - it helps you weed out the falsehoods from the facts. This is no different than what historians try to do with other written histories.
