Well... all I can say is that unbelievers have unions and babies with believers every day and have for as long as people have existed and giants were not born from the unions.
There are many places in the Bible where the angels are called, sons of God.
The Book of Enoch tells in detail about the unions the angels had with women.
Enoch was a main player in scripture and his writings are quoted several times.
To reject Enoch who walk with God and was not because God took him, you miss
out on the actual first Book of the Bible that is detrimental in understanding these
issues and others.
Demons are the spirits of the giants when they die. Not angels. angels are angels.
And there is no scripture that says they don't have DNA.
The Book of Enoch was scripture until it was removed by the Romans. Mainstream
Christians are taught that our Bible (choose your translation) is the Bible. The KJV
is the best translation, in my research, though it has many errors when compared
to the original texts in the original languages. All the translations after it get worse.
I could post all the references to grave errors but that is a topic for another day and
requires much study to except or deny and most wont do it.
But I will post evidence showing Enoch is indeed scripture. And it says clearly that
200 of the fallen angels took human woman as wives and born giants.
I will also post references to the "son of God" phrases almost always referring to angels.
Stay tuned.
Quotes from the Bible that are from 1Enoch
1 Enoch 10
1 Then said the Most High, the Holy and Great One spake, and sent Uriel to the son of Lamech, 2 and said to him: 'Go to Noah and tell him in my name "Hide thyself!" and reveal to him the end that is approaching: that the whole earth will be destroyed, and a deluge is about to come 3 upon the whole earth, and will destroy all that is on it. And now instruct him that he may escape 4 and his seed may be preserved for all the generations of the world.' And again the Lord said to Raphael: 'Bind Azazel hand and foot, and cast him into the darkness: and make an opening 5 in the desert, which is in Dudael, and cast him therein. And place upon him rough and jagged rocks, and cover him with darkness, and let him abide there for ever, and cover his face that he may 6,7 not see light. And on the day of the great judgement he shall be cast into the fire.
1Enoch 12
12 with them in all their uncleanness. And when their sons have slain one another, and they have seen the destruction of their beloved ones, bind them fast for seventy generations in the valleys of the earth, till the day of their judgement and of their consummation, till the judgement that is 13 for ever and ever is consummated. In those days they shall be led off to the abyss of fire: and 14 to the torment and the prison in which they shall be confined for ever.
The Book of Enoch has been proven to have been written before the New Testament.
And so it has to be where the quotes must have came from
2 Peter
4 For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment;
Jude 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.
Jude 1
14 And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints,
Enoch was verified as a prophet. He has a book. You should read it. There is information in it that sheds light on matters not taught these days in most denominations and that goes for Christian denominations. The best part about it is that Enoch prophesied in the first chapter of his book that his book was not for that generation but for the generation in the last days. And it is just recently getting popular and recognized as scripture by many who see in their Bible that He is indeed a prophet and he did write a Book. And God called him a righteous scribe.
1Enoch
1 The words of the blessing of Enoch, wherewith he blessed the elect and righteous, who will be 2 living in the day of tribulation, when all the wicked and godless are to be removed. And he took up his parable and said -Enoch a righteous man, whose eyes were opened by God, saw the vision of the Holy One in the heavens, which the angels showed me, and from them I heard everything, and from them I understood as I saw, but not for this generation, but for a remote one which is 3 for to come. Concerning the elect I said, and took up my parable concerning them:
The Holy Great One will come forth from His dwelling,
4 And the eternal God will tread upon the earth, (even) on Mount Sinai,
[And appear from His camp]
And appear in the strength of His might from the heaven of heavens.
5 And all shall be smitten with fear
And the Watchers shall quake,
And great fear and trembling shall seize them unto the ends of the earth.
6 And the high mountains shall be shaken,
And the high hills shall be made low,
And shall melt like wax before the flame
7 And the earth shall be wholly rent in sunder,
And all that is upon the earth shall perish,
And there shall be a judgement upon all (men).
