The Wickedness of Mankind
6And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them, 2 That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
3 And the Lord said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
4 There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown. 5 And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
6 And it repented the Lord that he had made man on the earth, and it grieved him at his heart. 7 And the Lord said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them.
Notice that the sons of God ( capital G) took for themselves (selfishness) all they chose. So the daughters of men(cains daughters, those who do not have a relationship with the lord, vagabonds) are regarded as inferior having no rights. So we see here that no only do the sons of God think themselves better, but also take the daughters of men by force.
Notice that God is grieved and says
3 And the Lord said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
So if the sons of God are in fact fallen angels or Gods angels who decided to rebell at that particular point, then why does God punish man for the sins of the angels?
6 And it repented the Lord that he had made man on the earth, and it grieved him at his heart. 7 And the Lord said,
I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air;
for it repenteth me that I have made them.So the fallen angels do a great evil but man gets the punishment and the blame, doesn't sound like justice. It's not justice either that the entire human race gets punished for the sins of the line of Seth, but often in the bible humanity is judged together, such as Noah's flood, but man doesn't get punished for the sins of the devil or fallen angels. In this verse God decides to destroy man and also repents that he made man, or regrets making man. There is nothing about the angels here, why doesn't God repent for making the angels, the very ones that supposedly brought this wickedness to mankind.
But if these sons of God are in fact of the line of Seth, then not only can they be accounted as Sons of God but also they are the ones that are accountable bringing God's punishment of a smaller lifespan and then also complete destruction.
4 There were giants in the earth in those days;
Dinosaurs
and also
after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became
mighty men which were of old,
men of renown.
why are there two sets of giants? One set is called mighty men, but the first set are simply called giants. We know that the second set are called
mighty men, but the first set are simply called giants in the earth, and in archaelogy records we have bones of giant prehistoric mammals or lizards. This could be the verse that explains dinosaurs.
9 These are the generations of Noah: Noah was a just man and perfect [1] in his generations, and Noah walked with God. 10 And Noah begat three sons, Shem, Ham, and Japheth.
11 The earth also was corrupt before God,
and the earth was filled with violence. 12 And God looked upon the earth, and, behold, it was corrupt; for
all flesh had corrupted his way upon the earth.
13 And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.
Violence filling the earth, man eating dinosaurs and giant violent men, the stuff of legends. There doesn't seem to be any record of giant lizards in the 7 days of creation, what if the sin of man caused a mutation in the lizard animals causing them to supersize just like the giants

Perhaps the sons of God being seth used their powers for evil. Remember that Noah a rightoeus man had the power to curse his son to be slaves for generations. The power of the tongue in an anointed man can move mountains, what if these old men of God used their power to create giant lizards

either that or their evil deeds, perhaps bestiality (passing a curse onto the animals)caused these giant lizards

Didn't God say to Adam ye are gods and back then the power of blessings and cursing was far more impactful. Wow the power that God has given man, maybe that's why people think that the fallen angels caused the mutation, they have forgotten the awesome power that God has given mankind, that we are made in his image

Also mans power is what does the witchcraft, why do the demons need man to do these things, if they the demons already have the power, maybe because they need mans words, their tongue to send the curse.
praise the lord for goodness and mercy in Jesus name.
