Yeah. My cousin (once removed) was just telling me about how my great-grandmother got saved and was trying to witness to her mom who was in the occult. She started at twenty-three and died at ninety, but wouldn't listen. Based on some of the examples, and being somewhat aware of other occult practices, I don't want to imagine what hundreds of years of hatred toward God would be like. Most of those generations would have known Adam, so there is no pretending God doesn't exist, when
the first man is there to tell you otherwise. It's just outright hatred and rebellion.
Old dog new tricks debunked. I'll have to tell my older colleagues that when they're being stubborn.

For the story, I want to try to make the distinction between what is fact and what is fiction. For the story, style might get tricky there, but for the archaeological aspects, I think I'll give specifics where I can, but be vague if I can't. Saying, for example, "two miles due east" or "further south" as the need arises.
I think I might do a narrative for the ancient portions, but have the modern and archaeological information be written like newspaper clippings or journal entries. Maybe have characters mentioned, but no one about whom we get much information. Those pieces might be kind of short, while the narrative chapters will be longer. I also really like the idea of interspersing Scripture and pertinent writings of the early church fathers to further build the contextual timeline throughout the ages.
