who begat the first Native Americans? What year according to Genesis? Whose property/"possession" were the Egyptians?
If we are going by the Bible (and science) mankind's birth was called the Garden of Eden, which science, studying fossil evidence, pinpoint to these origins being in the horn of Africa. Biblical stories appear to match up. The Hebrew language didn't count years. The word usually translated as 'day' is better translated as a new time period. Yes, that can mean a new sunset/sunrise (our day) or in could mean what we would call the next era, the next change. As I recall, science put this beginning (more or less) around 300,000 years ago.
Archbishop James Ussher (Church of Ireland, a branch of the Anglican Church) thought that the age of man could be calculated by counting back the generations between Christ and Adam. He (and the King James Bible) thought 'day' meant 24 hours, and 'generation' meant Father to son to grandson (etc). In the Hebrew, 'son' could very well mean son as we identify it today. Equally, it could mean 'descendant of'. (This can be noted in the use of the phrase 'son of David'.)
The Bible doesn't seem to specify the origins of Egypt, but it does have a fascinating history. King Menes is given credit for uniting the people into a nation, but it was a longer process than can be credited to a single man. An interesting note is that Pharaohs, were considered gods, there to keep order among the people. As far as who created the world, I believe that is credited to the sun god, Ra, also known by a couple of other names. If I recall correctly, one of these names was Amun. In any case, on earth he was pictured as a ram, and actual animal was worshiped as well.
As an atheist, here is a fox you can set among the chickens: Why did Yahweh use the blood of a baby ram to protect the Israelites from the last plague? Yes, at that young age, a sheep/ram is known as--and called--a lamb. We call Jesus the Lamb of God, and believe his blood cleanses/protects us. Male lamb...ram...Egyptians worshiped rams; the blood of a young lamb/ram protected God's people. I've always found that fascinating. What is even more fascinating are all the attempts to associate Jesus with the other gods of mythology fail miserably when looked into--while the obvious has been missed or passed over. (As a kid, I delved heavily into mythology--loved it. That's how I find it so easily to pick apart those who try to compare Jesus to other mythological gods.)
Anyway, I've gone on and on far too long. But I heartily recommend the study of Egyptian history, their gods, and their mythology. It's fascinating!
