"The sons of God saw the daughters of men that they were fair; and they took them wives..."

 Recently, some people have been talking about hybrids that existed before the Great Flood. According to their interpretation of Genesis, chapter 6, these creatures were the offspring of humans and extraterrestrial beings. They call these supposed creatures NEPHILIM. The strangest part of all is that even some atheists "believe" this...

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.

Genesis 6: 1-4.

Finally, when tempted by the Sadducees about marriage after the Resurrection in Matthew 22: 28-30, Jesus refutes this unfounded Nephelim hypothesis when He answered:

Therefore in the resurrection whose wife shall she be of the seven? for they all had her.

Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God.

For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.
