Yahweh is absurd because he developed organically from the evolution of Stone Age religion. He wasn't invented through some careful process of philosophical enquiry; he's a composite of other ideas, which themselves were improvised by people just telling stories about the world as they imagined it.
There is archaeological evidence that people used to worship fertility goddesses, but I'm not terribly surprised that some desert nomads ended up with a despotic sky lord instead of an Earth mother, or that he became popular amongst the Romans.
So, one thing about it that I will hold up as useful is as a stepping stone to the wide acceptance that there may be objective truths of ethics and objectively good applications of law.
Now, it was gotten to by fallacy and mythology, and no work was shown. It doesn't mean that several large aspects of the religion are wrong - think Incel cult, where there is a grain of truth at the front of a deep well of crazy.
But the fact is, I think just like there were truths to see about the implications of evolution by means of natural selection, there are some truths to see about evolution and survival by informational transfer, test, and selective duplication, and I suspect these boil down much the same to ethics, with strong hints from morality.
So there's that provenance.
But that's more religious history and pre-philosophy.
Then, other philosophers were prior to many biblical texts and said much the same things about the idea that all the world operates by singular principles including the rightness of the law, such as Plato.
A despotic sky lord he was. If he wasn't such a murderous bastard, I may never have see the lie of the book. That too has some value. And so too in filtering and identifying those who support a murderous bastard such as skydaddy.
