Chapter 6 of Genesis has this interesting passage:
"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 wives of all which they chose.."
The sons of God mentioned in Genesis were clearly not from this planet.
"There were giants in the earth in those day;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."
Could the "men of renown" be a reference to Atlantis in the Old Testament?
There is a definite distinction between men,the sons of God,and the offspring of the sons of God and the daughters of men.
