If Noah's Flood Happened?

You need to be briefer if you want useful answers. The warrior caste in many societies tends to be taller, Goliath being one example, and clearly some ethnicities are taller on average than others. Maybe they were the Hyksos people.

I don't think you need to assert such an ill-supported hypothesis to explain the very small proportion of texts that refer to the Nephilim. In general, there's a strong tendency for the most boring explanation to be the correct one.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
