Long Ago
There are passages that indicate the living waters were set long ago, at the time of Adam. Jacob references this too.
Job's Living Waters
The following reference indicates the living waters, the carrier of the text, were laid down long ago.
The likely time when the text would have been inserted was at the time of Adam. Before he was brought back to life.
To use the vocabulary here, laid down.
Implanted In Our Nature
The book of Jacob has a similar hinting reference.
Something is implanted in us.
This is normally spiritualized, but in nearly all cases a concrete physical interpretation will turn out to be correct. We are slowly coming out of the dark ages as we change our view of the text.
In any case bits have been revealed across time, but the reference copy may be buried inside every living human cell. In our nature.
Marked Us
The idea that we are marked, like a genetic branding, is hinted at in Ephesians chapter 1. There are several verses, likely heavily edited, but then a final restatement at verse 11.
We are marked from the beginning. Marked at the time of Adam.
More reason to think that Adam's family was marked genetically.
