Much wisdom can be difficult to stumble upon but is self-evident once known. Long-lived societies are sure to import all such wisdom from around them, then discover more for themselves over time.
I mean tangentially related, a while ago there was an article about how to safeguard nuclear waste storage for the next 100.000 years; one suggestion was to create a religion around it and its preservation. Something that can survive an intellectual step backwards. (Not unheard of; see the Greek and Roman societies of old. Their knowledge was lost for a long time, but Christianity survived. Of course their knowledge getting lost may be related to the rise of Christian religions as well)
Depends on how high you set the bar for 'survive'.
We have a few of the writing of Euclid, Archimedes and other Greeks, and mostly they weren't preserved for religious reasons.
I'm struggling to imaging something recorded in this draft that is useful, and not already known?
A lot of timeless wisdom is also obvious.
As another commenter said, it seems obvious to you because it's been incorporated into our culture.
For instance, I lived in Turkey for a few months, and I had a Turkish roommate who was a devout Muslim. He gave me an English translation of the Qur'an to read, and I gave him a Turkish translation of the New Testament. He decided he would come and show me the places where it must have been changed (since Islam teaches that Jesus was a prophet, but what he says in the New Testament obviously doesn't match what Mohammad said).
What was the first place he found that was obviously changed? Matthew 5:38-39: "You have heard it said, 'Eye for eye, tooth for tooth.' But I tell you, do not resist an evil person. if anyone slaps you on the right cheek, turn to them on the other cheek also."
Well, there's a good example for you: Either that seems like good advice, in which case you certainly got that from your culture; or it doesn't, in which case it's worth chewing over to get some wisdom out of it. :-)
What he said was something like that Islam says that when you're attacked, you should be strong defend yourself; and maybe let the other person know that you're not weak. So I guess he thought that this contradicted what Allah said elsewhere (through Mohammed), and therefore couldn't have been said by Jesus (since Jesus also spoke for Allah); and so must have been added in by someone later.
(To be clear, trying to repeat what I remember he said, not making any claims about what Islam does or doesn't teach.)
The thing is, the whole reason Jesus' statement stands out is because it does contradict our natural ideas about the right way to react. I can understand someone adding in fake stories about miracles or fake claims to be divine; but why would you add in fake teaching that's so counter-intuitive -- and on the face of it, so... pathetic?
His question honestly caught me off-guard; I was expecting him to bring up claims of Jesus' divinity, or his death and resurrection. "Turn the other cheek" is so firmly established in our culture as one template for "how good religious people behave" (a la Ned Flanders from the Simpsons) that it wouldn't have occurred to me that people would consider it "false teaching".
And because I was caught off-guard, I didn't ask him how he thought it came to be that way in the first place. Probably he hadn't thought that far. :-)
Now, in Muslim culture (I am again not an expert) it may be that they teach a more strict sense of a right to take revenge/justice on those that do them harm?
Jesus often says things hyperbolically to shock people enough to get them to think outside their boxes. It's a bit like that quote from Suits: “What are your choices when someone puts a gun to your head? ... You take the gun, or you pull out a bigger one. Or, you call their bluff. Or, you do any one of a hundred and forty six other things.”
In certain cultures, if you're insulted or attacked, people feel like they basically have to respond in kind. But this sets up a cycle of violence: someone attacks you, you "have" to attack them; but then they "have" to attack you back, and so on until one of you is more or less destroyed. (Furious 7 probably unintentionally demonstrated this perfectly: both the main hero and the main villain were revenging attacks done by the other on their own family.)
Saying "Turn the other cheek" is basically along the same lines as the gun quote: "What are your choices when someone smacks you in the face? ... How about this: You turn the other cheek. Or you ignore it and move on. Or, you do any one of a hundred and forty six other things. You don't have to respond in violence."
Note that the person you're replying to did not say that the bible was ALL timeless wisdom, or really say much at all about the overall quality of the bible.
There's no contradiction between the bible containing lots of timeless wisdom AND containing lots of utter nonsense and complete bollocks.
Even as somebody who is an atheist and who generally finds religion to be a blight on our society, I think one can find "timeless wisdom" in the bible mixed in with the other stuff. Whether that, on balance, makes it worth investing time in or not is another question.
Then again, that is probably how it was and when I read the old viking stories they are equally - if not more violent.
I have also enjoyed reading both the Viking age Håvamål as well as the ancient Proverbs (as well as a number of other sources).
However, many would say the entire compilation is a myth.

Catholic church takes care explain that officially (1):

Some people find that inconvenient.
(I mean, I'm not a bible scholar; just... it was, you know, one of those times when I unintentionally gave offense, and seems like something you should be aware of if you are trying to avoid flame wars.)
What if it's true though?
The problem you have is that the converse would be objectionable to Christians as you'd be saying God's new covenant achieved nothing.
I'm just saying this was something I stepped in by accident and that you should be aware of it.
