Flood Leftovers?

I’ve always been taught that Noah and his family were the only ones who survived the worldwide flood. But it says specifically that “only eight were saved by water.” I don’t know what that means for people elsewhere, but it seems to me to indicate that other people were saved, though I am not sure how.

And I’ve discussed before that the Nephilim existed both before and after the flood.

Genesis 6:4
“The Nephilim were on the earth in those days- and also afterward- when the sons of God went to the daughters of men and had children by them. They were the heroes of old, men of renown.”

Doesn’t that make you wish you knew what they had done? Their exploits? Are these the origins of most of the myths of heroes?

And what does it mean that the sons of God went to the daughters of men? Did angels have children with people? Did Adam and Eve’s children marry with the Neanderthal (or whomever)? What does that mean? It indicates a clear mix of some sort. Does it just mean that the righteous and the unrighteous joined together? It doesn’t seem that such a simple answer should be right.

Numbers 13:33 (This is much later after the flood.)
“We saw the Nephilim there (the descendants of Anak come from the Nephilim). We seemed like grasshoppers in our own eyes and we looked the same to them.”

Now remember this is when God’s people, those who are now called Jews, went from Egyptian bondage, back to the land that became Israel—land that had been given to Abraham. He had owned a LOT of land back then. And that doesn’t count what hadn’t been claimed for his descendants yet.

Were the Jews the original little people?

Were the Nephilim really giants? I have heard it said, although I don’t know because I haven’t looked into it that well, that giant skeletons have been found in the US in burial mounds that are long and broad. Does that make those people Nephilim?

I have read that the Celts were taller than the folks around them. Were the Nephilim Celts or are the Celts descendants of the Nephilim?

There were redheads in Abraham’s family. His grandson Esau was red, hairy. And David is described as “ruddy,” a word, I have been told, in Hebrew, that corresponds to the skin color of redheads. Now you don’t have to be red headed to get that skin color. (I have it.) But you have to have had redheads in your gene pool.
