Bureaucratic records, mostly. The Egyptians had a fondness for record-keeping.
Bully for you.
Are you going to even bother to try and address how this papyrus could have survived a year-long submersion?
Did they mention that a bunch of slaves once kicked their sorry @$$es and drowned them in the Red Sea?
No, which suggests that it most likely didn't happen. Like I said, the Egyptians were prolific record-keepers. As there is no other evidence that this Bible story is true, it's logical to conclude that it didn't happen.
Torah Scrolls are organic and eventually decay, at which point they have to be buried in a Jewish cemetery, next to the grave of a pious sage. But the original Torah Scroll exists in every kosher Torah Scroll in existence, which is written according to the strictest set of laws in existence to assure that each and every one is an exact duplicate of the original dictated by HaShem to Moses.
Even if such scrolls are 100% complete and accurate copies of the original such scroll, that is not evidence that the events described in such scrolls actually happened.
Besides, if the original Scroll still existed wouldn't you simply point out that it was written after the fact and is therefore unreliable?
Sure. Plus, there is no outside evidence for the claims in such scroll, so that also goes against its accuracy.
Interesting that nothing in the Bible can be accepted without outside corroboration while things written by ancient pagans are accepted on faith.
You seem to be missing, or ignoring my point. Even if the contents of the 5000+ year-old papyrus cannot be independently verified, the mere existence of such ancient papyrus writings is evidence against a global flood.
Unless, of course, you can explain to me how a fragile substance like papyrus could survive a year-long submersion?
Where had that papyrus been? Many documents were sealed in jars; if inverted (lid down) and the body of the jar did not leak, that would keep water out.
