Traditionally attributed to Moses (Though even his historicity is called into question). The authorship of the Torah by Modern Scholars is that it was completed during the time around 7th to 9th century b.c. Hence the documentary hypothesis which looks at the books drawing from the J, the E, the P, and the D.
That said it does not mean that the stories themselves did not exist prior to that formation, but they were not nearly as concise as they were now.
There is plenty of ways to investigate the claims of the older books.
Particularly when it starts meshing in history.
Genesis Parallels are found in many mesopotamia cultures. Even evident in literary styles, seen in the two creation stories in Genesis 1 and 2 and also in the flood story "two of every kind, or 7 clean pairs and 2 pairs of every kind"...Did Noah send a Dove or a Raven? The story of the flood matching up with the epics of gilgamesh for instance.
Abram, Jacob, Isaac, all up in the air if they were real or actual composite characters.
But even when you step away from that.
Exodus mentions a mass evacuation of a number that could easily tally up to 2+ million people. There have been no records as of that that has Egypt ever having such an exodus. Especially when they left in such a rush, there would have been things left behind...and of course when did it actually happen? But so far there is no evidence of that, the Egyptian empire was huge and stretched a good distance, what may have been called an exodus may have really just been small scale rebellions.
What Secularist books have you read on the Canaanite wars? Because none of the articles and research have indicated that these lands were privy to the massive attacks lead by Moses and Joshua (anything can be justified by those who need it to be). Rather it seems to indicate that things were relatively peaceful. It also seems at least with current evidence that the Israelites were a subset group of Canaanites...of course as more evidence comes out there is much to learn. Digressing though, Jericho as you mentioned the burned wall which was crushed does not fit the timeline as described by the Bible, with most archaeologist agreeing that the wall feel several hundred years before the narrative in Joshua.
The five kings slew by Joshua, have yet to turn up evidence of their existence, but again I do not believe the absence of evidence is the evidence of absence necessarily.
The destruction of Tyre did not go by the way Ezekiel claimed it would. Tyre was destroyed not by Nebudchanezzer which is made explicit in the chapter but rather by Alexander the great, though now it exists.
There are other countries or groups who would be told they would be destroyed forever but later were told remnants would remain (looking at you Jebusites and Edom).
It is said that the Lord sent an angel to kill somewhere along the lines of 185,000 of Sennacherib men and that he was forced to retreat, and was later killed by his sons. Sennacherib actually did get assassinated, by whom isn't actually recorded in history, however (and yes he could have been lying):
Because Hezekiah, king of Judah, would not submit to my yoke, I came up against him, and by force of arms and by the might of my power I took 46 of his strong fenced cities; and of the smaller towns which were scattered about, I took and plundered a countless number. From these places I took and carried off 200,156 persons, old and young, male and female, together with horses and mules, ***** and camels, oxen and sheep, a countless multitude; and Hezekiah himself I shut up in Jerusalem, his capital city, like a bird in a cage, building towers round the city to hem him in, and raising banks of earth against the gates, so as to prevent escape... Then upon Hezekiah there fell the fear of the power of my arms, and he sent out to me the chiefs and the elders of Jerusalem with 30 talents of gold and 800 talents of silver, and diverse treasures, a rich and immense booty... All these things were brought to me at Nineveh, the seat of my government.
Hezekiah's actions according to some archaeologist nearly bankrupted Judah and it was during the time of his Son Manasseh there was peace.
Now of course there is actually some mentions by Josephus that some disaster had befallen Sennacherib's men and Herodutus mentions it as well, perhaps that is the disaster that had befallen his men, but how closely related that is to Judah (which he left to go put down a coup), is lost to history currently.
There are definitely good amounts of theological and poetry in the Bible that are beautiful (Book of Job, Song of Solomons, story of Esther and Ruth), there are great lessons that can be drawn from them. However as history? It's not holding much weight currently as it once did.
but there is so much more left to discover so I withhold any actual judgement.
You have posted quite a few claims here that any one would require much time to resolve. I almost never refuse a challenge and am not doing so here. However I can't start down all these roads in a single post and do justice to any of them. I will take on whatever you think is your best claim and then the rest in order if you wish. However doing them all at the same time is meaningless and impractical. Pick any one of these and we can attempt to resolve it. The Bible is a very sophisticated book and an old one which almost never allows neutrality. Despite the fact it is the most textually attested work of any kind many times over in ancient history there are constantly people who think they can argue it away even if all their predecessors failed to do so. You have given a short statement from one side of the coin but there is another side that is inexhaustible that needs to be included and then the best side chosen. I can't present that other side beyond a drive by staccato status unless one claim is chosen and sufficient time devoted. Your choice.
