The Hebrew word for giants is “Nephilim.” The word translates a Divine being that co-habituated with women! Most but not all Bible scholars believe the Divine beings were fallen angels! So why would Satan and his followers want to cross breed with women on earth? We know from the scriptures Satan will never repent and salvation is not possible for him and his followers! The reason Satan did this was to spoil the redemption plan God had for man! Only a pure human race could be redeemed! Only God becoming man could bring about redemption! So what did God do to solve this problem? He brought a world wide flood and saved only Noah and his family! This brings a challenge to the church in that science now has developed animals with human blood and organs! There is fossil evidence of humans dying in the flood! These humans are known as the Neanderthal men! The difference between the Neanderthal’s and modern man is about 1.3 percent of mitochondrial DNA sequences. Here are some questions and answers that will help us! How did the Neanderthals go extinct? They died in the flood. Why is there no evidence of a pre-flood man? There is much evidence of pre-flood men! They are the Neanderthals! Why is the Neanderthals genetically distinct from modern man? Neanderthals had only the first genetic reset, but modern man had both the first and second genetic reset! Why do we have his Neanderthal genetic mutations but he does not have ours (modern man). He is our ancestor. Our mutations were developed after the flood, so we have both Neanderthals and modern man mutations; he has only pre-flood mutations! Why did Neanderthals interbreed with modern man? He could not! Modern man was separated from him by the flood! Why are Neanderthals found in such diverse places? The flood deposited them over large geographical area’s. Why is Neanderthals physiologically and anatomically superior? His DNA is closer to Adam! Where does Neanderthals fit into post flood Biblical genealogy? He does not! We know from DNA tables of nation peoples (Genesis Chapter 10) and subsequent generations; none has the Neanderthals genetic signature! Source: Back to Genesis
