Here is how the Nephilim were produced, according to the word of God.
4 There were giants on the earth in those days, and also afterward, when the sons of God came in to the daughters of men and they bore children to them. Those were the mighty men who were of old, men of renown.
- There were giants on the earth in those days, and also afterward, when the sons of God came in to the daughters of men
Not through some "genes" that were carried on the Ark by Noah's daughters.
If we want to "guess" and use our theories, then sure, we can just make up any ole doctrine about any subject.
If we are to be guided in our understanding then we need to read and believe what the word of God so plainly says.
- There were giants on the earth in those days, and also afterward...
The way the Nephilim were produced before the flood is the way they were produced after the flood.
- ...when the sons of God came in to the daughters of men
Here are some relevant biblical fact that one needs to consider:
Nephilim giants are not mentioned in the genealogy of Genesis 5, which serves as the context of Genesis 6.
There is no mention of sons of God in the genealogy of Genesis 5, which serves as the context of Genesis 6.
The term sons of God is an Old Testament reference to angels.
[
Job 1:6 -
Job 2:1 -
Job 38:7]
The New Testament writers referred to them as angels.
Jude, who speaking by the Spirit directly quotes Enoch, describes angels who did not keep their proper domain, and left their own abode, were associated with sexual immorality.
6 And
the angels who did not keep their proper domain, but left their own abode, He has reserved in everlasting chains under darkness for the judgment of the great day; 7 as Sodom and Gomorrah, and the cities around them in a similar manner to these, having given themselves over
to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire.
Jude 6-7
Peter says it this way -
4 For if God did not spare
the angels who sinned, but cast them down to hell and delivered them into chains of darkness, to be reserved for judgment; 5 and did not spare the ancient world,
but saved Noah, one of eight people, a preacher of righteousness, bringing in the flood on the world of the ungodly;
2 Peter 2:4-5
Peter directly associates these angels with the incident during the days of Noah.
