In no place in the Bible the angels or other creatures are called sons by God.
Only men are made at image of God.
“Now there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them.” - Job 1:6 (KJV) -
"He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the form of the fourth is like the Son of God."
- Daniel 3:25 (KJV) -
"Then Nebuchadnezzar spake, and said, Blessed be the God of Shadrach, Meshach, and Abednego, who hath sent his angel, and delivered his servants that trusted in him, and have changed the king's word..."
- Daniel 3:28 (KJV) -
more to add:
Gen_6:4 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.
Job_1:6 Now there was a day when
the sons of God came to present themselves before the LORD, and Satan came also among them.
Job_2:1 Again there was a day when
the sons of God came to present themselves before the LORD, and Satan came also among them to present himself before the LORD.
Job_38:7 When the morning stars sang together, and all
the sons of God shouted for joy?
Jud 1:4 For there are
certain men crept in unawares,
who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.
Jud 1:5 I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not.
Jud 1:6 And
the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.
Jud 1:7 Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.
Jud 1:8 Likewise also these filthy dreamers defile the flesh, despise dominion, and speak evil of dignities.
1Co 11:9 Neither was the man created for the woman; but the woman for the man.
1Co 11:10 For this cause ought the woman to have power on her head
because of the angels.
Sounds like pretty bad angels huh? Exactly what harm could come to a human woman from these angels? Could it be these angels are the ones said to have been "before of old ordained to this condemnation" and "saw the daughters of men that they were fair; and they took them wives of all which they chose" in Genesis 6? Could the child have grown into huge, evil giants that plagued the world for generations?

The Scofield Bible in 1901 was the first to successfully propagate the Idea that the ‘sons of God’ were the descendants of Seth and the ‘daughters of men’ were from the ungodly line of Cain. Some proponents of this theory use to try to state that angels can’t reproduce, when in effect this actually agrees with Enoch 15 in saying that there will be no need to. Some problems with this theory are: 1st genetic problems develop from inbreeding not from marrying other tribes or races. 2nd none of the early church fathers taught this. All who commented on Genesis 6 agreed the ‘Sons of God’ were angels. Sources like Josephus, Justin martyr, Irenaeus, the Septuagint, and many others. Justin Martyr stated that 1 Corinthians 11:10 referred to the Genesis 6 story.
Early Church fathers who taught that the sons of God were Angels were:
Athenagoras (chapter 25), Clement of Alexandria, Titian, Irenaeus, Tertullian, Methodius, Commodianus (chapter 3), Josephus, Felix, Ambrose of Milian, and Origen. The codex Alexandrias and three later manuscripts use the word angel instead of sons of God in Genesis 6. Origen and Tertullian refer to Enoch as Scripture.
