"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."
(Genesis 6:1-2)
The KJV version says this:
"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 6:4)
The NIV says it this way:
"The Nephilim were on the earth in those days--and also afterward--when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown."
(Genesis 6:4)
Remember, it was Moses who wrote this book, not Noah. By Moses' time, the giants (Nephilem) Sons of the "gods" were indeed heroes of old, and men of renown; names like those we find in Greek mythology and other supposed mythologies as well.
It is my guess that if you were to see an angel, and it commanded you to worship him as a god, you would.
