Consider the following translations of Genesis 6:1-4
KJV:
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 an hundred and twenty years. 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.
NKJ:
Now it came to pass, when men began to multiply on the face of the earth, and daughters were born to them, that the sons of God saw the daughters of men, that they were beautiful; and they took wives for themselves of all whom they chose. And the LORD said, "My Spirit shall not strive with man forever, for he is indeed flesh; yet his days shall be one hundred and twenty years." 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.
NIV:
When men began to increase in number on the earth and daughters were born to them, the sons of God saw that the daughters of men were beautiful, and they married any of them they chose. Then the LORD said, "My Spirit will not contend with man forever, for he is mortal; his days will be a hundred and twenty years." The Nephilim were on the earth in those days-- and also afterward-- when the sons of God went to the daughters of men and had children by them. They were the heroes of old, men of renown.
ASV:
And it came to pass, when men began to multiply on the face of the ground, 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 that they chose. And Jehovah said, My spirit shall not strive with man for ever, for that he also is flesh: yet shall his days be a hundred and twenty years. The Nephilim were in the earth in those days, and also after that, when the sons of God came unto the daughters of men, and they bare children to them: the same were the mighty men that were of old, the men of renown.
CEV:
More and more people were born, until finally they spread all over the earth. Some of their daughters were so beautiful that supernatural beings came down and married the ones they wanted. Then the LORD said, "I won't let my life-giving breath remain in anyone forever. No one will live for more than one hundred twenty years." The children of the supernatural beings who had married these women became famous heroes and warriors. They were called Nephilim and lived on the earth at that time and even later.
RSV:
When men began to multiply on the face of the ground, and daughters were born to them,
the sons of God saw that the daughters of men were fair; and they took to wife such of them as they chose. Then the LORD said, "My spirit shall not abide in man for ever, for he is flesh, but his days shall be a hundred and twenty years." The Nephilim were 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. These were the mighty men that were of old, the men of renown.
NLT:
When the human population began to grow rapidly on the earth, the sons of God saw the beautiful women of the human race and took any they wanted as their wives. Then the LORD said, "My Spirit will not put up with humans for such a long time, for they are only mortal flesh. In the future, they will live no more than 120 years." In those days, and even afterward, giants lived on the earth, for whenever the sons of God had intercourse with human women, they gave birth to children who became the heroes mentioned in legends of old.
The message (which requires extensive study):
In the days of and after Noah (the Great Flood), angels (sons of God) married humans (daughter of men) and created a race of individuals called the Nephilim. These creatures formed the basis for Greek and Roman mythology.
Why should ths fact be hidden? We burned people at the stake in the 1600s for being witches. If you told those people in Salem or the inquisitors in Spain that a race of superbeings still existed, the American Indians would probably be the only race still living on the planet.
