Took a humanities class on the development of religion. As another poster commented, the Bible is a collection of books and stories that can be found even on other religions and older texts. Given that this a collection of works dating back over thousands of years, my recollection is more of generalization that can point to what to look for rather than provide extreme specifics.
Take the Odyssey, it can be compared to books in the Bible such as David and Goliath, the flood, etc. There is others such as the epic of Gilgamesh demonstrating the use of gods giving humans epic powers and fighting one eyed evil giants. The use of daemons converted into demons in the Bible. For example, It is said a daemon is someone of 2 genders in one body, similar to a hermaphrodie however one part was holy (iirc), and would serve to be a useful companion rather than an evil force against you.
Now imagine you got all these motherfucking books everyone else made.
I’ll title my small book: Ye Old Plagiarism
One, the Greeks fucking hated writing in anything other than pentameter or stuff like that. Naturally poems and the like must have their lines numbered.
Two, the Roman’s also hated writing normally, expect lines and wacky rhyming schemes.
Three, the Bible is written and it ended up looking like this.
