The battle is about sin and possibly also genetics. I find it curious God uses the term “seed’ when he prophesies of the warfare of the “seed of the serpent” vs the “seed of Eve”. The fallen ones defied God,Satan tempted man to sin, interfered with our genetics by intermarrying with our women, causing much multiplied sorrow and sin until God was moved to destroy our early civilization by a great flood and cause certain of the fallen ones to be bound.(see Jude who quoted Enoch) Satan is the only one left to be dealt with and Christ defeated him on the cross and via the resurrection! The mop up action is going to be horrendous!
So what about all that is false interpretation?
Deception designed by Satan to create the obvious seeds of doubt, ambiguity and confusion.
Hanging in and denying alternative interpretations of man's creation and remaining unyielding to the power of suggestion that Jesus is unnecessary -- it's not easy staying the course.
This genetic contamination was also a reason God told his men to kill every woman, man, and child. Even to killing the horses and dogs. As the Jews were enslaved in Egypt, Canaan had over 400 years to plant giants in God's promised land for the freed Jews to have to overcome. David picked up 5 rocks when he killed Goliath because Goliath had 4 brothers. All would have to die in the end.( 2 Sam 21:22)
Some have speculated that these Chimera's are still around today with DNA markers making them unsavable for heaven. We are told to not take marks in Lev 19, and could it possibly be that Satan marked his and God marks His with the Holy Spirit with clean DNA. Possibly these markers would breed out over 7 generations( sins of the father) but then the marker appears again down the line that generate ungodly people. IMO, in the last days, the Antichrist will require you to mark yourself with his name to mark you as his. Satan is a counterfeiter and hates God's mark on His people. Just theory of course, but we know that genetics is important to the "seed" prophesy.
