Jesus said we will be as the angels following the resurrection of all, not being given in marriage. Do you think that implies any gender? Do you think God really has a gender? Why would immortal, eternal spirit beings have need of such things? The flood was brought about by the state of men's hearts, being that they were evil. I tend to agree with the sons of God being of the line of Seth, and the daughters of men being from Cain's line. There are people alive today who are very tall. Robert Wadlow is now deceased, but he was almost nine feet tall.
Gen. 6
5Then the LORD saw that the wickedness of man was great on the earth, and that every intent of the thoughts of his heart was only evil continually. 6The LORD was sorry that He had made man on the earth, and He was grieved in His heart. 7The LORD said, "I will blot out man whom I have created from the face of the land, from man to animals to creeping things and to birds of the sky; for I am sorry that I have made them."
