First time reader of this thread - I am really impressed that you were reading 5 chapters of Genesis per day and in King James English on top of that!
I am reading from the Holman Christian Standard Bible and my reading goes in fits and starts. It will probably take me a couple or few years to get through the Old Testament.
Civ 4 comes and goes for me. Currently playing Baldur's Gate TOTSC over here and on a third consecutive day of rest from that.
Regarding persecutions - I will take this as a reminder to pick up a copy of
Barnabas Aid.
You can add to your list America's downward spiral.
No doubt you will pick it up again right where you left off.
I have not gone through all the posts in this thread. It was already 14 pages long by the time I found it. When I think of burning questions, I will ask:
1. According to Scripture, is a 6000 year-old earth a take-it-or-leave-it proposition? Can an Old Earth Theory be reconciled with Scripture through gaps and intellectual gymnastics and Relativity theory? Can a Young Earth Theory be reconciled with modern day science? Where does Uranium come from? Does the unleaded gasoline in my car have Carbon-14?
I note Genesis 1:16 references the creation of the Sun and the Moon, and this was already on the fourth day.
2. As an attempt to answer your question about Cain and where did his wife come from - Chapter 4 records the birth of Cain and Abel. Genesis 5:4 says he fathered sons and daughters. I would say that Adam and Eve had daughters along with Cain and Abel, but they were not mentioned in Chapter 4, where Cain took a wife.
Going forward to Genesis 29:31-35, you have Jacob and Leah having four sons, Reuben, Simeon, Levi, and Judah. Then she stopped having children. Chapter 34 tells the story about Dinah, a daughter Leah bore through Jacob. (EDIT: First mentioned Genesis 30:21.... ooops

)
3. When did the Biblical Flood occur? Creationists claim all these fossils and rock formations were created by the flood waters coming and going. Evolutionists claim it was millions of years of erosion and there were many mass extinction events. (Next time I am really bored maybe I will look up how to calculate rates of erosion and abrasion and see if the Creationist claim that the Grand Canyon was dug by 5 miles of water receding over 54 days or so is physically possible.)
4. What happened to the Dinosaurs? Did God tell Noah (Genesis 6:19) to go get two of each kind and put them in his Ark? And did Noah look at Mister T. Rex and shake his head and say "nuh-uh."
5. Chapter 10 is also known as the Table of Nations. Where did the Native Americans come from?
Genesis 10:6 "Ham's sons: Cush, Egypt, Put, and Canaan." Your translation calls Egypt "Mizraim." Wait a minute - Egypt was a man?
Genesis 10:14 is your first mention of where the Philistines come from.
6. When did the Tower of Babel event of Chapter 11 occur? What was the world population at this time?
7. Who built the Great Pyramid at Giza? It is much more sophisticated than the technology we say was available to the people living there at the time. It certainly does not work like you are playing Civ 4 and research Masonry, build a Stone Quarry and chop down a bunch of trees.
That's all the questions I can think of so far. After this, we are into Chapter 12 and my current reading is up to Chapter 29.
