Is it possible that the only person left on earth whose DNA was not corrupted by the inter-marriage of Sons of G-d and humans was Noah and that is the reason only Noah was kept alive. Was these Sons of G_d somehow plotting to destroy humanity's DNA through intercourse (breeding)???The Book of Enoch refers to these creatures as Nephilims, but the Holy Bible refers to them as Sons of G_d why? In Genesis it talks about creating man in our image refering to G_d or G_d and Sons of G_d was this phrase in the singular or pluaral???
One more additional question: If these creatures were destroyed during the great flood then how did the giants appear on the earth after the flood (i.e., David & Goliath)???
