These are not ordinary humans because these giants came as the fruit or results of a cross breathing between the sons of God and the daughters of men.
These giants in Genesis are not with human nature. Why? Because they are even mighty they are strong and they were men of renown meaning. In science, we must not think that these are real humans. They are not real humans because they are real humans and only affected by the excessive growth hormone produced by the pituitary gland they can be weak. But this is the opposite: they are giants but they are strong. Who are they?
Let us read the story from the book of Genesis.
And it came to pass when men began to multiply on the face of the earth and daughters were born unto them that the sons of God saw the daughters of men that they were fair and they took them wives of all which they chose and the Lord said my spirit shall not always strive with man for that he also is flesh yet his days shall be a hundred and twenty years.
There were giants in the earth in those days and also after that when the sons of God came in and the daughters of men and they bore children to them. The same became mighty men which were of old men of renown and God saw that the wickedness of man was great in the earth and that every imagination of the thought of his heart was only evil continually.
You see the story: these are not ordinary humans because these giants came as the fruit or a result of a cross breathing between the sons of God and the daughters of men. The sons of God mentioned in these verses are angels. Why do we know they are angels because God himself said my spirit shall not always strive with men. He also is flesh because man is flesh.
In conclusion, God as a spirit will not strive with flesh or with man. He will stripe or contend with the spirit also
We have the ideas that these sons of God are spirit and they are angels in the Bible. Angels are called the sons of God in the Bible.
