You might be surprised to find out that the New Testament is a sequel to the Old Testament, an older book. You might also be surprised to know it comes from the Hebrew Bible – the Tanakh – which also contains the Torah.
Although it gets ridiculously complicated, the Old Testament is thought, by scholars, to have been written throughout centuries by hundreds of authors. Essentially becoming an anthology of stories passed through the minds (and perhaps overactive imaginations) of thousands of individuals across human history up until that point. These stories were selected and compiled in different ways in the Tanakh, and the multiple versions of the Bible, in order to promote their respective beliefs.
Who knows the multitude of Gods generations of authors were referring to before they were blanketed under one religion? I don’t and this is becoming increasingly convoluted and complex. To save from making wild assumptions to fit my theory, I’m going to leave this be for now. You’re welcome.
